Hello people,
I have a project with some lightly used MultiGrid 48/3000/35-50. They're too good to be scrapped, but didn't come with a manual, so I'm looking to power an off grid house with two of them in parallel.
I understand from the training we need to have them perfectly balanced with even length cables that aren't over rated.
I'm curious to know how to rate the circuit protection for a generator input and system output.
Each unit will pass through 50a but the existing generator will only be 20a total contribution at best.
Should the system have a 10a MCB for each inverter input?
With 3kW inverter output and surge rating to 6kW, each inverter could have a 32a MCB on the output, with a single downstream 63a main switch?
There will be a colour control and a 48/250-85 solar reg with 4kW PV as well. Would it be feasible to add a Fronius Primo at a later date?
Cheers
