The 4.6-6.5 kW Single Phase GoodWe ES Hybrid Solar Inverter Battery Charger with Grid Injection is an inverter that can charge batteries and can also be connected to the grid. They are the most interesting inverters because during the day they charge the battery with the surplus energy and can be used at night to be as self-sufficient as possible. At night the battery provides us with electrical energy and when the battery is about to run out, it would start consuming energy from the grid. This type of inverter is specially designed to reduce the electricity bill as much as possible. Their price-performance ratio is extremely attractive and the return on investment is very interesting. It can charge all types of 48 Volt batteries such as PYLONTECH 48V batteries which are the most common and well known on the market. This inverter can work with or without batteries.
