Hi!
We have a permanent off-grid installation in a garden in Germany (no grid, no generator) with 7 kWp solar and a 24V 12 kWh lead-acid battery (so around 6 kWh usable).
We currently have a MultiPlus Compact 24/2000/50-30. Which has a nice low standby consumption, which seems to be important in the winter.
But at least in the summer the 2000VA of the inverter is too small for us, as we have a lot of solar and also some consumption:
1-2 fridges running, some times a pump for irrigation, the occasional lawn mower and we like to use an electric stove for cooking and baking. And the inverter shutting down due to overload is always a pain. Electrical car charging is also nice.
Now, we were thinking about 1-2 multiplus 24/5000 or about 1 quattro 24/8000.
Is it possible to normally have the existing multiplus 24/2000 running (for the low idle) and switch on the quattro automatically, maybe using PowerAssist?
Or should we rather get rid of the multiplus 24/2000 and have two multiplus 24/5000 running in parallel?
Do you have similiar installations? What would you buy?
