Hello community!
I'm trying to find out how to set up the small hybrid solar installation in my vacation house. I love the flexibility of Victron, but on the other hand I am worried I'll miss, that some functionality is not supported by the inverter/charger I'll choose.
What I want to build:
- solar installation on DC side
- charging 48v ~10kWh LiFePo4 battery
- 4-6kW inverter
System is sized to power the whole house during the summer season and in winter when we are not using it (standby mode, only basic devices and running pumps of central heating)
How I want it to work:
- I'd like it to power the house form battery for as long as possible (keeping battery health in mind, so probably not lower than say 25% SoC) and if its not enough to use only off-peak grid power
- charge battery from the sun
- if excess sun power available - dump it to heat the water
- if battery SoC below certain low level - charge it from the grid to the set level, but only in off-peak tariff (time constrained)
- if grid unavailable, switch to off-grid with anti-islanding in mind - requirements of Polish network to be fulfilled.
What is my question:
The question is if I am able to set all I pointed above to be executed by one of the inverters listed below?
- Multiplus II 48/5000/70-50
- Quattro 48/5000/70*
- Quattro II 48/5000/70*
- Multi Solar RS
- Easy Solar 5kva
If by more than one of them - what's the difference I should care about?
