Hello!
I posted in the welcome forum but I thought I would move this to the proper forum.
Our park (seasonal) has horrible voltage. Up until this weekend my plan was steering toward a Victron Multiplus II to limit shore current and supplement the power using solar and batteries. But this weekend exposed how bad the park can get, it was down to 87V when I was pulling 15A, so with my Hughes Autoformer I was seeing 95V inside. I now think I want to totally isolate myself from the shore.
So I am wondering what product I should be looking for. I was hoping it could still have a charger section where I could limit draw to maybe 8A (then park power would be 95V or higher) so that shore could supplement solar for charging the batteries. But I don't want it passing shore to my RV, only charge. When I talked to Victron PowerAssist will just supplement the current, if I am feeding it 95V it will pass 95V on to my trailer.
Should I just be looking at a couple of products instead of an all in one? Like a 95-120V input capable charger, then a separate inverter and MPPT?
We only go up for two nights at a time, 3 days max. I have a monitor on it and he usage for our longest time in trailer is 41.2kwh in a 44 hour period. That period contains about 20 hours of largely direct sunlight.
So for safety I want to say I need to supply 45 kwh in a 48 hour period with 20 hours of sunlight. I can fit (4) solar panels, looking at 220W panels. I feel safe in pulling 8A from shore as a charger.
Calculators for sizing the batteries aren't really clear for this kind of setup, nor do I know what kind of product I should look at. The trailer is 30A so I would want to size for that so we can use the trailer as intended.
Any ideas are appreciated.
Thanks
Ryan
