If an off-grid PV system will rely solely upon PV as a charging source (no generator, no other renewables) then it is necessary to ensure that a PV source is properly sized for this role. The PV source size should be checked to ensure that it can supply sufficient current to properly charge the energy storage system. If lead acid batteries do not regularly receive an adequate charging current - typically because the PV source is undersized relative to the energy storage system - they will begin to experience sulfation and they will last for fewer cycles.
