How many batteries do I need for my house?

It depends on how much power you use in the hours you want to cover. Share your inverter size and your evening load and we will work it out with you.

Is lithium worth the extra cost for backup?

Over the full life of the system, often yes. Lithium lasts far more cycles and uses more of its rated capacity, so the cost per usable unit is competitive.

Solar and backup batteries in Kenya

Solar and mains backup systems store energy for the evening or for a power cut, so the battery is cycled every day. Deep cycle gel, AGM and lithium iron phosphate units are all suitable, with lithium giving the longest cycle life.

We can supply single batteries or a matched bank, and advise on the charge controller or inverter settings that will get the most life out of them.
