The Solar Management Unit (SMU) is the new generation of Solar Charging device which helps to convert normal inverter to solar inverter and helps to priories use of Green Energy generated from Solar Array. green energy SMU are designed for highest efficiency zero drop technology integrated with advanced microprocessor.Solar 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.To promote Solar Energy and thus contributing to the environment. To make Solar Energy more affordable. To develop and manufacture an easy to install/maintain system that works with existing domestic inverter/storage batteries. To monitor battery charge levels at all times. To give preference to Solar PV charging. This helps in reducing AC grid electricity units consumed by the customer.
