RITIKA SystemsSolar PV Interfaces are designed for customers who have already invested in a domestic inverter and battery set, and now desire to switch to solar power. They may use this system to integrate solar PV charging in a simple and cost efficient manner.
Being an-add on to the existing domestic inverter, this offers a very cost efficient way of converting an existing domestic inverter (already owned by the customer) into Solar Power Conditioning Unit (Solar Inverter + Battery Charge Controller). Interface can automatically sense 12V/24V system and work accordingly.
