  Y&H SUNT-5.5KW hybrid inverter is suitable for residential and light commercial use, maximizing self-consumption rate of solar energy and increasing your energy impendence.During the day, the PV system generates electricity which will be provided to the loads initially. Then, the excess energy will charge the battery via SUNT 5.5KW. Finally, the stored energy can be released when the loads require it. The battery can also be charged by the diesel generator to ensure uninterrupted supply in the event of grid blackout.

Peak shaving and valley filling applications:
Use utility Timed charging to the battery (valley electricity, when electricity is cheap).
Solar energy and utility will charge battery(Solar and battery energy storage supplies power to loads during peak hours. And when the electricity bill is cheap, Use utility Timed charging to the battery).
Solar energy will be the only charging source even if utility is available.(Peak power, when the electricity bill is high.Set utilities not to charge).

Self-issuance for self-use:
Solar energy will supply power to the load as priority, and the excess power will charge the battery. When the solar panel power is insufficient, AC bypass will supplement(In times of high electricity costs, you can reduce the battery AC charging stop voltage to avoid charging the battery at peak utility power).
Peak Cutting and Valley Filling. When electricity is cheap, the battery timed charging. Use storage power during peak hours.
On/Off grid mode: Solar power first supplies the home load and fully charges the battery, then the excess power is transferred to the home grid. Reduces electricity costs. (Zero Export To CT)
UPS mode, solar panel or battery power. You have the flexibility to set the battery discharge voltage depth. Ensure that there is enough power to power critical loads in the event of a power outage.

Four modes can be choose when charging battery:
Utility first
Solar first
Solar and Utility(default)
Only Solar

Three Output modes can be choose:
Utility first
Solar first
SBU Priority
