Warranty:  5 years.

Warranty applies to systems which have a battery capacity of at least 2 x daily consumption.

example, if daily use is 12kwh,  a minimum requirement of 24kwh capacity is expected


Through experience, we find that ANY battery chemistry, when cycled 100% every day with high charge and discharge currents has a limited lifespan, some  LiFEPo4 batteries make it to about 3 months when worked hard
