LiFePO4 lithium & lead-acid batteries — sized, supplied and installed for homes and businesses in Nairobi, Kiambu & Machakos.
A solar battery stores energy your panels produce so you can use it at night or during a KPLC blackout. Lithium (LiFePO4) batteries are now recommended — they last 10–15 years versus 3–5 for lead-acid. Prices run from about KSh 32,000 for lead-acid to KSh 160,000+ for a 5 kWh lithium unit (indicative, 2026).
Watch: Understanding Solar Battery Storage in Kenya
We recommend lithium or lead-acid based on your usage and budget, and size storage to your real evening load — not a generic package.
We supply branded batteries with real warranties, not unbranded cells that fail early. What we sell is what we stand behind.
We match battery voltage to your inverter and controller and install to standard — protecting your warranty and your home.
Including the Mageta Island Solar Project, with installations across Nairobi, Kiambu and Machakos and after-sales support throughout.

The Kenyan market is dominated by two technologies — lithium and lead-acid — with lithium now the default recommendation for most buyers.
Best for: Most homes & businesses seeking long-term value and daily use.
Best for: Lowest upfront cost; backup-only or infrequent use cases.
Best for: Budget-constrained, well-ventilated sites; less frequent use.
The key figure buyers miss: a lead-acid battery should only be discharged to ~50% of its rated capacity. A "200Ah" lead-acid unit really gives you ~100Ah of usable energy. A lithium battery of the same rating gives you nearly all of it — which is why one lithium battery often replaces several lead-acid units over its life.
Lead-acid wins on upfront price. Lithium wins on lifespan, usable capacity, maintenance, and safety — and usually on total cost over the system's life.
| Factor | ⚡ Lithium (LiFePO4) | Lead-Acid (AGM) |
|---|---|---|
| Upfront cost | Higher | Lower |
| Lifespan | ~10–15 years | ~3–5 years |
| Charge cycles | 6,000+ | 1,200–2,000 |
| Usable depth of discharge | ~90–95% | ~50% |
| Maintenance | None (sealed, built-in BMS) | Some (especially flooded) |
| Weight | ~⅓ of equivalent lead-acid | Heavy |
| Performance in heat | Handles heat well | Degrades faster in hot areas |
| Best for | Daily cycling, long-term value | Tight budgets, occasional backup |
Our general guidance: for a system you'll use daily, lithium (LiFePO4) is almost always the better long-term investment. Lead-acid can still make sense for a tight initial budget or light backup use. We'll recommend based on your usage and budget — not push one option. Ask us to compare both for your situation →
Battery storage is measured in kWh. The right size depends on how much you use in the evening and how long you want backup to last.
Don't undersize or oversize. Too little storage and you lose power in the evening; too much and you pay for capacity you never use. Many lithium systems are expandable, so you can start with what you need and add capacity later. Send us your evening usage for a free sizing →
Battery pricing is driven by capacity, chemistry, brand and warranty. Ranges below are indicative — verify current pricing before purchase.
| Battery | Indicative Price (KES, 2026)* | Notes |
|---|---|---|
| Lead-Acid / AGM 200Ah (deep cycle) | ~KSh 32,000 – 48,000 | ~50% usable; ~3–5 yr life |
| Lithium 12V / 24V 200Ah (~2.5 kWh) | ~KSh 100,000 – 130,000 | Drop-in lead-acid replacement |
| Lithium 5 kWh module | ~KSh 120,000 – 160,000 | Most popular home size; often expandable |
| Large lithium (10 kWh+) | up to ~KSh 500,000+ | Whole-home / commercial |
Remember to compare on cost per usable kWh over the battery's life, not just sticker price — a cheaper lead-acid battery replaced three times can cost more than one lithium battery over 15 years.

Six factors that separate a good battery investment from an expensive mistake.
Size to what you actually consume after sunset — not your total daily usage. Oversizing wastes money; undersizing leaves you in the dark.
For any system cycled daily, lithium delivers better value over its life. Consider lead-acid only for tight budgets or infrequent backup.
Aim for at least 5 years. Longer warranties signal manufacturer confidence and typically mean better build quality.
Battery voltage (12V / 24V / 48V) must match your inverter and charge controller. Mixing incompatible components voids warranties and risks damage.
Many lithium systems let you add battery modules later. Starting smaller and expanding is often smarter than oversizing upfront.
A battery wired incorrectly is a safety and warranty risk. Professional installation ensures your system is safe, matched and fully covered.
A solar battery must be matched to the other components Kamatye supplies and installs.
Manage charging and discharging. Battery voltage must match your inverter exactly.
View inverters →Regulate charging current to protect battery life and prevent overcharge.
View controllers →Solar panels only generate power when the sun is shining. A battery stores the surplus produced during the day so it's available at night, on cloudy days, or during an outage. Without storage, solar energy is only available while the sun is up.
In a hybrid system the battery provides backup and reduces how much you draw from KPLC. In an off-grid system it's essential — there's no grid to fall back on. The battery works together with your inverter and charge controller, which manage how it charges and discharges.
