System Operation

Inverter Working Modes
The PowerDepot A1 supports several different working modes which can be programmed on the SolarHope App.

Self Used Mode
Go to the “Hybrid Work Mode” menu, and select the “Self Used Mode” work mode. Under Self Used Mode, the priority of PV energy will be Load > Battery > Grid, which means the energy produced by PV gives priority to local loads, excess energy is used for charging the battery, and the remaining energy is fed into the grid. This is the default mode to increase the self-consumption rate.

Excess PV Energy
When there is plenty PV energy available, the PV energy will be first consumed by loads, the excess energy will be used to charge the battery. Then, the remaining energy will be fed into the grid.

Limited PV power
When the PV energy is not enough to cover all the loads, all the PV energy will be used for load, and the remaining part will be supported by the battery. If this does not satisfy the load, more power will be taken from the Grid.

Time-Based Control Mode
At the bottom of the page in the SolarHope App, you will see an option for “Time-based Control”. By enabling this mode, you can control the charging and discharging of the battery. You can set the following parameters based on your requirements:

• Charge and discharge frequency: one time or daily
• Charging start time: 0 to 24 hours
• Charging end time: 0 to 24 hours
• Discharge start time: 0 to 24 hours
• Discharge end time: 0 to 24 hours

You can also choose whether to allow the grid to charge the battery, which is disabled by default. If the user enables the “Grid Charge Function” , the “Maximum Grid Charge Power” and “Capacity of Grid Charge End” can be set. When the battery capacity reaches the set value of “Capacity of Grid Charge End”, the grid will stop charging the battery.

Feed-in Priority Mode
Go to the “Hybrid Work Mode” menu, and select the “Feed-in Priority Mode” working mode. Under this mode, the priority of PV energy will be Load > Grid > Battery, which means the energy produced by PV gives priority to local loads, excess energy is fed into the grid, and the remaining energy is used for charging the battery.

Excess PV Energy
When there is plenty of PV energy, the PV energy will be first consumed by loads, if there is excess PV power, then the excessive power will be fed into the grid. If there is any remaining PV power, it will redirected to charge the battery.

Limited PV Energy
When PV energy is limited and can not meet the feed-in grid power, the battery will discharge to meet it.

No PV Input
The inverter will first discharge the battery energy for home load consuming when no PV input is detected. If the demand is not met by the battery, then the inverter will consume energy from the grid.

Back-up Mode
Go to the “Hybrid work mode” menu, and select the “Back-up Mode” working mode. Under this mode, the priority of PV energy will be Battery > Load > Grid. This mode aims at charging the battery quickly, and at the same time, you can choose whether to allow grid to charging the battery. Disable Grid Charging In this mode, the battery can be charged only with PV power, and the charging power varies depending on the available PV power.

Excess PV power
When there is plenty of PV energy, PV charges the battery first, then meets the load requirements, and the rest is fed into the grid.

Limited PV power
When PV energy is limited, PV gives priority to charging the battery, and the grid directly meets the load demand.

Allow Grid Charging In this situation, the battery can be charged both with PV and grid.

Excess PV power
When there is plenty of PV energy, PV charges the battery first, then meets the load requirements, and the rest is fed into the grid.

Limited PV power
When the PV energy is not enough to charge the battery, the grid energy will charge the battery as required. Meanwhile, the grid energy is consumed by loads.
