Specific batteries for use in off-grid photovoltaic systems. AGM, GEL , Lithium
Batteries ideal for those wishing to reduce the purchase price. Optimal performance is obtained by discharging the batteries no more than 30%: in this case you get an estimated average life of 4-6 years (depending on model). Technically the batteries can can be discharged in higher percentage (always variable depending on model) without damage, but the battery life is shortened.
Batteries for best performance. Can be discharged up to 80-90% and extimated lifetime of 10 years
