UTL Sunpack 1025 Solar PCU Price Specification

Solar Home PCU (Sunpack) is a solar hybrid inverter which utilizes both the Solar Power and Grid Power to charge the batteries with giving priority to solar power. Solar power is of the first priority while charging. This means that when Solar power is available, the batteries will be charged with it only, irrespective of whether Grid power is available or not. It is designed to give you the maximum advantages from the Sun and thereby reduces your Electricity costs.

Sunpack is very easy to install. It fits your budget and also helps to cut your electricity costs. So, it is double advantage to the user!! Unlike other sources of energy, Home PCU and the Solar Panel do not emit harmful gases and residue in the environment. Thus, it helps in keeping the environment clean and healthy.
