If you already have solar panels, you know they work best when the sun is shining. But here in Uganda, evenings, cloudy days, or a sudden power cut can leave you wishing you had a way to keep that sunshine for later. That’s exactly what a solar battery does.
A solar battery stores the electricity your panels produce during the day so you can use it later at night, during rainy weather, or when UMEME decides to rest. Without storage, all that extra energy your panels produce simply goes unused once your immediate needs are met. With a good battery, you have power ready whenever you need it.
At Fern Engineering & Supplies, we supply, install, and maintain solar batteries for homes, schools, offices, hospitals, and businesses across Uganda. Whether it’s a small home setup or a big commercial installation, we provide batteries that fit your needs and budget.
We have different battery options from powdered Lithium-ion batteries that are long-lasting, efficient, and compact. Lead-acid batteries, the more affordable ones that work well for smaller systems.
For bigger projects or specialized setups, we also offer advanced battery banks and hybrid storage systems.
Our goal is simple — to help you keep your power even when the sun goes down.
At Fern Engineering & Supplies, we don’t just drop off a battery and leave. We give you a complete solar storage solution.
We start by checking your actual power needs — how much energy you use in a day, which appliances matter most, and how many hours you want backup for. This way, we give you the right size and type of battery for your lifestyle or business.
We supply batteries from reputable brands that have been tested in Ugandan conditions, this means they handle our heat, frequent charging, and varying loads without giving up after a short time.
Our technicians install your battery neatly and safely, connecting it to your panels, inverters, and existing electrical system. We also make sure it’s optimized for the best performance.
We can set up monitoring so you see exactly how much your battery is charging and discharging.
For long life, we offer maintenance services like cleaning terminals, balancing cells, checking wiring, and replacing parts before they fail. If something stops working, our repair team moves fast so you’re not left in the dark.
How long will my battery last?
It depends on the type and usage. Lithium-ion batteries can last 8–15 years. Lead-acid batteries usually last 3–7 years with good care.
How do I know the right size for me?
We’ll calculate based on your daily use, the appliances you want to run, and how long you need backup. A home with just lights and a fridge will need less than a busy office with multiple computers.
Can I add a battery to my current solar system?
Yes. Most systems can be upgraded, though we may need to adjust the inverter or wiring.
Are lithium batteries worth the price?
For many people, yes. They last longer, need less maintenance, and save space — which means they’re cost-effective over time.
Will my battery work when it’s cloudy?
Yes, though charging may be slower. We can set it up so it can also charge from the grid or a generator if needed.
Can I run my whole house on solar batteries?
Yes, if your system is sized for it. But many people choose to run only essential appliances so the battery lasts longer during an outage.
Do batteries need maintenance?
Lithium batteries need very little. Lead-acid batteries need more care — like topping up water levels and cleaning regularly.
Are solar batteries safe?
Yes. Our systems have built-in safety features to prevent overcharging, overheating, or short circuits.
Can I add more batteries later?
Yes. Many solar batteries systems are expandable, so you can increase storage as your needs grow.
How will this save me money?
By storing your own solar power instead of buying electricity or running a generator, you cut down your monthly bills and fuel costs.
A solar battery is what turns your solar panels into a full-time power source. Instead of wasting extra energy during the day, you save it and use it when you need it most — whether that’s during a blackout, at night, or during expensive peak hours.
At Fern Engineering & Supplies, we help Ugandans keep their lights on, fridges running, and businesses moving, no matter what UMEME is up to. From small home systems to big industrial battery banks, we’ve got the right solution for you.
Call us today or pass by our office to talk about the best solar battery for your needs. With the right system in place, you can sit back and say, “Power cuts? That’s no longer my problem.”
