Hello,
I am looking to supplement my Multiplus II 5000 48 (with two pylontech US5000 48 4.8kw) batteries to draw power from my hydro system during the dark / snow season on the mountain.
The hydro system provides direct AC 200-260V depending the water situation, but generally stable 230V 50+ HZ 250-300W power output. I could stabilize this further by running the through a current stabilizer to get even more smoother output.
My question is though, can I directly expect to plug it into the Grid-input (AC Input) in my multiplus, or will there be problems? I've understood that the capacity of the generator should usually be 2x the capacity of the inverter, so in this case around 8000 - 9000W which surely is not the case.
Can I use the input regardless? Couple of scenarios in mind:
- set multiplus to use hydro grid input only to charge batteries when available
- set multiplus to bypass battery charge with hydro grid input available and use it only for to run the direct house ac? for any given moment, if I don't run the gas heater, the loads are between 50-150W max. The system is used to run household items around 2.6kwh consumption daily.
At least, the Multiplus II should then be set up to not input any extra from the solar system (4x150W panels) to the grid side.
Any other issues or suggestions I should take into account? I've seen many people using DC systems with MPPT hooked up, but this is not an option with mine.
And yes, I do understand, that the 1.5A is low on the battery charging side, but imagining situation where the 1.5A is constant and the house draw is minimum when I am away (below 50W constant, this should be enough to sustain business for perioids of time when there is snow on the panels or I am away.
