The Wattsonic hybrid inverter can output the direct current(DC) from the rooftop solar PV array into alternating current(AC), so your home or business loading can use it directly.
The Master BMS can monitor the state of the whole battery system in real time, and keep communication with inverter to adjust charge/discharge and protection strategy dynamically according to the real-time battery running state.
Wattsonic high voltage battery modules are integrated with slave BMS, keep sensoring the voltage and temperature of each individual cells, and balancing the cells during charge and discharge.
In this working mode, when the power from the PV array is sufficient, PV power will supply the loads, battery, and grid by the following sequence: Loads>Battery>Grid.
PV power will supply the loads with priority, and secondly charge the battery if exceed PV energy, and then feed to the grid. (You can set the power to the grid to 0W if the local grid doesn’t allow through APP or inverter display).
When the PV power is insufficient, the battery will discharge to supply loads, and the grid will join in if the battery power is not enough.
In this working mode, the customer can set the maximum allowable power from grid("Pmax") through App or inverter display. When the loads consumption less than the Pmax, loads are supplied by the PV array and grid together.
When the loads consumption more than the Pmax, the power exceeded Pmax (cannot be higher than the inverter max output power) will be supplied by the inverter. PV power will take the priority to supply loads and if not enough, the battery will support the real-time loading immediately.
* To realize the “Peak Load Shifting” function, the load power that exceeded Pmax has to be within the inverter max output power, otherwise, the inverter will only output the max power which allowed.
In this working mode, the inverter will use the power from PV or grid (Set by App) to charge the battery with full power and top priority until it is fully charged, and as long as the grid is there, the battery won’t discharge.
When the grid is cut off, power from PV and battery will suppy real-time loading connected to inverter back-up port immediately within 10ms.
* During UPS mode, if battery long time no discharge, the inverter will discharge and charge battery periodically(every 1 week) with small current roughly 1A to to reset battery SOC.
In this working mode, the customer can set time-based scheduled charge and discharge by App, inverter will use the power from PV or grid(selectable by APP) to charge the battery in the scheduled period.
Inverter will use power from PV and battery to supply loads in the scheduled period and the insufficient part will be supplied by the grid.
In the purely off-grid mode, power from PV will supply the back-up loads firstly and then charge the battery if there is surplus PV generation.
When the power from PV is weak, the battery will discharge to supply back-up loads together with or without PV.
In this working mode, once battery full and real-time loading can be satisfied, inverter will automatically reduce PV generation to prevent injection into the grid.
