So I just got the proud new owner from a used 25ft Class A Motorhome.
It has the standard RV-power Lead setup.
1 Chassis Battery
2 House batteries
A completely oversized 5500w generator
Currently the house batteries can charge from the Converter or the Engine.
Requirements:
We are using the RV about once a month for a long weekend and then like 2-3 week long trips.
Since batteries are getting cheaper by the day, I got the dream of running the A/C at least during the night from battery (noise) it used about 4-8kwh through a night.
I know solar will not cover what I use in many occasions.
And since the All-in One systems are coming with substantial chargers (2-3 KW) - I can just program it that it starts the generator before night time for an hour or two to recharge the batteries.
I can probably add 2x 330-400w panels to roof. Maybe 3 when I eliminate one of the vents and the antenna.
I mean you get the 5kwh batteries from Signature Solar or Big Battery for like $1500-2000
Or DIY one, Probably need somewhere between 10 and 20kwh of storage.
The question now - the 12V system works, well -
Should just add the All in One - before all the RV stuff? Leave everything in RV side alone and basically plug the RV into the All-in one system and the other side in the Generator/ Shore power?
Next question the RV has a 30A plug - A 3000w All in one should be sufficient? But I why the heck did they build in a 5500w generator?
24V/ 48V MPP? Growatt? Any other products?
Thanks!
