Product Description

High Speed with high Performance

UTL`s solar management unit (SMU) is embed with a high speed microcontroller which increases the performance of the solar system. Solar management unit provide ability to perform its task more reliably and efficiently.

High Reliability with Longer Operational Life

It is highly reliable and it has longer operational life. Solar management unit can be operated in extreme environment conditions and can be operated at temperature range that lies in 0°C to 60°C.

Prioritize Solar Power over Grid Power

SMU ensures priority usage of solar energy over government electricity (grid) to reduce grid consumption. In daytime condition, the system will give priority to solar energy and use grid power only when the solar power is insufficient to sustain the load requirement.

Increase the battery lifetime

SMU utilizes four stage battery charging algorithm that enhances the battery lifespan. In bulk stage SMU feeds the battery installed to it a constant boost charging current until its voltage reaches 14.4V and the float current, then in absorption stage it maintains this voltage above 14.2V for 3 hrs.

Automatic/ Manual Operation

The system can work as a domestic inverter and a solar inverter automatically or manually through a switch except in night condition. In night condition, first it will harvests the stored battery energy then it will work as normal domestic inverter.

Inbuilt Protection to Avoid Battery Undercharge and Over-charge

SMU has the capability to charge a solar battery which goes in deep discharge condition. It can charge the battery if the battery voltage during discharge reaches up to 8V per battery. Solar management unit uses four stages to charge the battery i.e. Boost, Absorption, Float and Equalization. This feature protects the battery for being over charged.

Very Low Consumption in Idle State

It have very low idle consumption, in idle state it consumes less than 20mA current which makes it more efficient than any other solar management unit.
