First pidt, if I've put this in the wrong section please let me know. Thanks in advance to any who have thoughts.
I live in a trailer. This brings several challenges. I'm far from shore power. Increased power draw means an ever decreasing voltage drop. Plus everything downstream works harder. That said solar is probably not an option in my current location. I need more power but only intermittently. When I do, my supply voltage can drop to 85V.
Enter the utility shed. It's outside my living space and contains my washer and dryer. I router my shorepower there (1 x 120V/20A + 1 x 120V/15A).
I'd like to build a 48V 120V battery inverter system with the possibility of future solar support. I'd like to top charge from one or both of my power feeds, and use only inverted power. This power should be 120V - it does not have to be on a single bus, but at least 30A has to be available for the trailer. With ideally at least another two 15A circuits for use outside the trailer (I cook outside, washer, dryer are outside, and yes my dryer is 120V apartment size).
So probably looking at 7200W.
Will seems pretty happy with the EG4 systems from a value and function standpoint. Would they work with solar offline? Can they charge from mains? Or are there other systems I should consider?
Price is a big consideration. I don't mind doing more work, and I can run wire (ice worked with low and high voltage, and feel I could do anything including building from cells). But if I save a month of time and get a warranty I'm not too proud to choose the smart way.
My annual consumption averages around 400KWh a month. But that's the part I measure (in trailer). So it might be closer to 500KWh.
Ideally I'd like to be able to use one, or two shore power options. Even possibly considering adding a generator in the future but that could use one of the shore power inputs. So if for example I had only 15A shorepower I could run the generator during daylight for a couple hours to charge up for the over night quiet time.
At some point I want solar. But where I am now the trees make it unlikely until I move.
Thoughts? Advice? Discreet build with batteries and seperate mppt chargers with an inverter or is there a single unit which I could just add a second mppt to?
Btw I have about 24"x24"x60" to build in. I figure that should allow enough room? And the waste heat will keep my laundry machines from freezing in the winter ??
Thanks!
