PCU is a Solar Power Conditioning Unit (PCU) which uses Solar energy (primary) and also the power from grid (secondary), to charge the batteries as well as to feed to connected load. Since usage of power from grid is secondary, grid power is only used when solar energy is not present and battery voltage level reduces to a certain level. Grid power is also needed when solar power is reduced to a certain level and battery voltage is reduced to a certain level. PCU uses an advanced technology named MPPT (Maximum Power Point Tracking) to extract maximum power from the solar panel. The overall system is compact and easy to install.
Available Range:1 KVA , 2 KVA , 3 KVA , 5 KVA , 6 KVA , 7.5 KVA , 10 KVA.
