Solar Management Unit (SMU-1)

SMU is designed for solar /mains power supply system. Professional Software are applied as the control center to fulfill intelligent system control. LCD will indicate the working state. It`s easy to use and there are two automatic operational voltage modes, 12V/24V.

Protection:

Our SMU has the function of self protection from overload, outside and inside short circuit, reverse connection, PV panel reverse current, over charging and discharging etc. During the short circuit and overload. Overcharging protection Can be used for all panels Over discharging protection Fail Safe and cannot be damaged by accidental wiring mistakes advanced design with simple plug and play technology. No need for complicated adjustment.

LCD indications :-

Solar ampere Battery voltage Battery status Brand Name Mains Voltage Load on mains/inverter Load on solar/mains.

Features :-

Mode 1:

Inverter working like normal grid inverter, when solar is available the battery will be charged by the solar power .

Mode 2:

When solar available battery getting charged with solar and mains , when battery fully charged mains will be stopped , and when battery gets low to less than 50 % mains will connect automatically .

Mode 3:

When solar available battery getting charged with solar , mains charging will be stopped and load on mains.

Mode 4:

When solar available battery getting charged with solar , mains charging will be stopped on that time and load will depends upon mains , and when battery gets low than 50% mains will connects automatically
