Work modes: Feed in Priority
Priority:load>grid>battery
This mode applies the area that has high feed-in tariff and export control.
The PV generated power will be used to supply the local loads firstly, then export to the public grid. The redundant power will charge the battery.
WelsonPower 10kWh Solar Hybrid Generator the combination of battery, inverter and charger. Our Solar generator is plug and play, what you only need between the solar panels and load is our production.The generator also means the solar energy storage system.
Our solar lithium ESS is hybrid, this means it supports on grid model andoff grid model. As a result, there is no waste of energy there. And our product can also choose the priority of main and solar.
