How to Extend your inverter battery backup time


If you’re using an inverter set then I’m sure you’re already seeing its benefits. One challenge you’re probably already facing is your battery backup time not lasting as long as you would really like it to. Although I’d highlighted some tips to maximize your inverter setup in my previous post, this will focus on your battery.

You battery bank is measured in AH (with a voltage rating too) and determines how long your inverter can power its current load. It’s important you don’t mix this up with your inverter’s kVA rating. To help you understand the difference easily:

Inverter kVA rating determines how many appliances you can power at a time
Battery AH rating determines how long your inverter can sustain your current load (appliances you have on)

How to extend your battery backup time

Unless your batteries are damaged, there are some techniques you could employ to significantly increase your backup time (how long the battery powers your appliances before it goes flat):

Integrate a battery equalizer

Uneven charging and discharging is one reason why you might not be getting the most out of your batteries. When you have batteries connected in series and any charges to 100%, all others stop charging even if they’re just about 70% charged. When discharging, if any goes flat then all others too stop discharging even if they’re still at about 70%.

This uneven charging and discharging is as a result of the batteries not being 100% identical (even if they’re of the same brand and specs) and it builds up over time. This not only cheats you out of battery time but could cause the batteries to wear easily due to over-charging and over-discharging

What a battery equalizer (Battery Management System) does is to ensure that the batteries are charging and discharging at the same rate so you have optimal charging and discharging.

Know how to read your current battery level

In business, they say “If you can’t measure it, you can’t improve it”  The same applies to your battery bank. If you don’t know how to tell what your current battery level is then how do you know when its time to put off heavy appliances to save power? The battery level is hinted on the Inverter’s monitor but you’ll have to wait to see it because lots of other info are displayed at intervals.

Some inverters display battery bars while others only show current battery voltage. For such inverters, you take note of the battery voltage when fully charged (this will be indicated with a Battery Fully Charged message) and when empty (the inverter emits a steady beep to indicate). This way, you know your battery level at any given time and can adjust your usage accordingly.

Switch to energy saving appliances

One way to boost your battery time is to avoid running heavy appliances on the inverter (at least not for long). Your Home Theater system alone could be hogging 360 – 1,200 Watts; that’s huge! Reducing the number of appliances you have on at a time isn’t all, you should go the extra mile to switch to energy saving appliances.

Instead of those 60 – 100 W bulb (that cause your house to feel hot), switch to 3 – 12 W energy saving bulbs. I agree they are more expensive but the extra battery time you’ll get would mean less money spent on Fuel + Generator maintenance over months. click here to shop for energy saving bulbs 

Concentrate activities that require power

Having a routine helps you utilize your battery backup time effectively. From experience, I’ve learnt that I tend to be careless with my power usage when I don’t have a schedule for when the inverter should come on and for how long. For example, you watching your favorite TV show only to realize you had not been charging your phone just when you’re about to power off the inverter. Now, chances are that the fan or other appliances were on while watching TV. Leaving the inverter on just because you want to charge your phone means the fan and some other appliances will stay on longer which translates to more battery consumption.

Upgrade your battery bank

Upgrading your battery bank is another way to extend your battery time. This is a costly approach but sometimes, your battery bank just isn’t enough. You don’t necessarily have to change your entire setup or discard your current batteries, just add more batteries. The number and specs of the batteries you’ll need to buy depends on the specs of your current setup and what you really wish to achieve. I’ll give an example:

Lets say I have a 2.5 kVA; 36V inverter. This means the battery bank must equal 36V no matter how many batteries I connect. Lets say I opt for 12V 100AH batteries. I would need at least 3 connected in series so that it equals 36V (12+12+12).

Now, if I wish to upgrade by battery bank; I’ll have two main options

  1. Buy another 3 100AH 12V batteries so I have 6 100AH batteries in all
  2. Discard my 3 100 AH 12V batteries and buy 3 200 AH 12V batteries

if you want to get your inverter battery call 08154892727

As you can see, upgrading my battery bank depends on my preference, I might not want to sell or give away my 100 AH batteries so I buy more and get a 6 battery rack. I might – on the other hand – not like the clutter of many batteries and opt for fewer, more powerful batteries.

Tips to extend the life span of your batteries

Apart from extending your battery backup time, you should also take good care of your batteries so they last longer and here are some tips:

  • Ensure to use the rubber battery terminal protectors to avoid dust and rusting of the terminals
  • Ensure your inverter setup is in a well-ventilated area to prevent heat from damaging the batteries
  • Avoid overcharging and deep discharging (using the battery till empty). Go for an inverter that automatically protects your batteries against these
  • Avoid leaving the battery idle for a long period of time without any form of charge or discharge activity

How to reduce your electricity bill in Nigeria

With the steady increase in electricity tariff and cost of fuel, it becomes imperative to reduce your energy consumption hereby saving you thousands of naira in electricity bills which can be put to good use with other things.

Welcome to another episode of energy talk with Solarity, we hope to solve most of your energy related challenges.

The average Nigerian pays over 60,000 to 100,000 naira a year for electricity. This means that electric bills alone can take upwards of 5-10 percent of a person’s income. Unfortunately, there are hundreds of things involved in one simple bill. And figuring out exactly what to focus on is the most difficult part of lowering your monthly energy costs.

You can tremendously reduce your electricity bill by having an energy-efficient household this means reducing your energy consumption by using efficient appliance and energy-savings strategies. An example is to swap out incandescent light bulbs with compact fluorescents (CFs) or LEDs, and boosting insulation levels in your home.

Energy efficiency is always the most affordable and environmentally sound place to start when approaching renewable energy. Experts estimate that for every naira you spend on efficiency improvements, you can save N3 on the long run. So where is your money best spent?

A 2020 study by Vanpeux global Synergy Limited  identified seven major household energy uses:

  • Space Heating—29%
  • Space Cooling—17%
  • Water Heating—14%
  • Appliances—13%
  • Lighting—12%
  • Other (stoves, ovens, microwaves, coffee makers, dehumidifiers)—11%
  • Electronics (computers, monitors, DVD players, TVs)—4%

Recommendation on energy conservation

  • Energy conservation works together with efficiency, changing your energy-use behaviors (for example, turning off the lights when you leave a room, or adjusting the temperature of the air condition at night). Apply the basic principles of conservation and efficiency to all of your energy choices.


  • Since space heating and cooling take such big bites out of the energy pie and in turn your energy bill, Energywatchng recommends improvement in your home’s insulation and reducing air infiltration can be a smart first strategy. Sealing draft-prone areas, the points at which dissimilar building materials converge or the building envelope is penetrated, reduces uncontrolled air infiltration. Combine this with increased insulation, and upgraded window and doors, and you can reduce the amount of heating, ventilation, and air-conditioning needed to sustain a comfortable household temperature throughout the year. Passive strategies, such as solar retrofits, movable shading devices, and/or strategically placed landscaping, can also provide energy-saving benefits when it comes to heating and cooling your home.

  • Some strides have been made in more efficient water heating, including better-insulated tank-style heaters (both gas and electric) and the much newer “hybrid” water heaters that feature heat-pump technology. For retrofit situations, consider adding extra insulation to your pipes and tanks to reduce energy losses. Solar hot water systems can also drastically improve a home’s water-heating efficiency, cutting your water-heating bills by 40% to 80%.


  • Upgrading to energy-efficient appliances and electronics can greatly improve your household’s energy efficiency. From LED lamps to horizontal-axis washing machines, many gains have been made in reducing energy use. Before you start shopping, surf the Energy Star website to find the most efficient appliances that will suit your needs. Most especially your appliances you run longer like your TVs, refrigerator etc.


  • Higher-efficiency lighting—mostly in the form of LED lamps—has begun to enter the mainstream, with quality bulbs readily available. Compared to their incandescent counterparts, LED lamps use one-tenth of the energy and last up to 40 times as long. They contain none of the hazardous mercury present in compact fluorescent  (CF) bulbs, but are more expensive than CFs.


  • Last but not least, you can identify the energy-wasters—known as phantom loads—in your home. Unfortunately, many household electronics—even when “off”—constantly draw energy. Unplugging them, putting them on plug strips that can be switched off, or using dedicated switches can defeat these phantom loads and provide additional energy savings.

how to maintain solar panels

Information on Cleaning and Maintaining Solar Panels

Owning solar panels is a big investment, and solar panel maintenance is necessary to ensure your long-term benefits. Solar panels can provide you with renewable solar energy for the next 25 years or more. But how do you maintain them? Are they like your car, requiring regular tune-ups to stay in peak condition? Or are you supposed to just leave them ? Here are a few tips for solar panel maintenance and solar panel cleaning

Tips for Maintenance of Solar Panels

  • Keep solar panels out of shade as energy production becomes inefficient when they are kept from absorbing any sunlight.
  • Keep an eye on the solar panels and make sure the inverters are flashing green lights. If they are not flashing, you are losing money by no longer compensating for your electricity use.
  • Document the day-to-day performance to improve solar panel maintenance. It is important to write down how much energy has been produced at a consistent time every day and make special note of dates where it is very cloudy. Some of the results will be inconsistent. (Your manufacturer would be able to provide you with the best monitoring system for your solar panels.)
  • Monitoring systems help you see how much you are benefiting the environment and how much CO2 you are emitting into the atmosphere. They can also help you know how much you could benefit from the feed-in tariff scheme.
  • You can also see information about your solar panels servicing on a wall-mounted display when you are at home.
  • If you have no time in cleaning solar panels, you can install automated cleaners that work like sprinkler systems or even schedule appointments with solar panel cleaning companies.
  • Luckily, because solar panels have no moving parts that could be affected by rust or break down, solar power maintenance may not be needed.  provides you with a free of charge and with no obligation service that allows you to request quotes and compare different systems, so that you can find the most suitable for you. Just fill in the form  

Cleaning Tips for Solar Panel Cleaning

  • Solar panel cleaning kits come in very handy for cleaning solar panels. Inside the kit, you will find a biodegradable soap, a wiper, and a small brush or brush with a longer handle. Mix the soap in the bucket with water. Instructions are provided on the bottle. Dip the brush in the bucket and begin gently wiping the solar panels. You can use plain water or a soft brush to remove any grime or dirt that has built up on the panels.
  • How to clean solar panels has never gotten easier! Clean solar panels when they are moist or wet so any dirt so residue that is stuck on them can be wiped off easily.
  • Never use an abrasive sponge or soap for your solar panel cleaning as you may scratch the glass. The best way to clean solar panels by using a soft rag or biodegradable soap.
  • It is important not to use harsh materials when cleaning solar panels as they could cause damage, and solar panels are costly to repair.  provides you with a free of charge and with no obligation service that allows you to request quotes and compare different systems, so that you can find the most suitable for you. Just fill in the form  
  • If you clean often, you might be able to just run a hose along the panels to remove any dirt. Fewer calls on solar panel maintenance.
  • For your safety and the safety of others around you, use a long handled wiper to clean the panels while you are standing on the ground.
  • If you must get on the roof, take proper care as once you begin cleaning, the roof becomes slippery and you could slide off when you get down, so use safety ropes or a harness for support.
  • Always watch out for dirt on the solar panels to make sure it doesn’t build up since they can absorb sunlight better when they are free of dirt.
  • Many people question, do solar panels need cleaning? – The answer is yes. Depending on the type of panel you have, you might be weekly or monthly in cleaning solar panels. Your solar panel manufacturer should be able to advise you on this for solar panel cleaning.
