The Voltronic Axpert VM1000/12 is a high quality Puresine, high efficiency inverter + mains battery charger + 40A MPPT solar controller, all in one.
Heavy tests have been done by ourselves in these 3-in-1 electronics.
A powerful high efficiency 1 kW nominal puresine inverter, a 20Amp battery charger an a sophisticated 40amp MPPT solar charge controller.
Mains or generator, batteries and solar array can all be connected to just one electronic device, drastically reducing needed installation space.
The programmable parameters on the unit is pretty fascinating and the unit is even more configurable than the better known brands.
Total priority can be assigned to the solar array (energy used directly, and rest taken from battery if realtime solar production is not enough, and prioritize solar charging to mains/generator input, all this fully programmable by user).
As its an all-in-one product, another advantage is that all voltage readings are very precise,as its a single unit with all the integration being perfectly calibrated.
The LCD displays lets you toggle thruogh the fully configurable menu's optimizing preferences for each user

The GOODWE NS inverters are transformerless solar inverters. They make the use of the conventional electrical network making grid feeding possible so they allow self-consumption, grid zero installation or even selling to the grid . The GW5000NS allows upto 6,5kW of solar panels to be attached.
During the day this energy is available and can eliminate most of the electricity bill.
