AC charging is good for a backup. Wire it for 120v 15amp service and carry an extension cord. That way if you need it - you can look for a usable 120v outlet.
I have been using my Multiplus for 3 years now 24/7. It’s a great inverter.
Here is maybe a better idea:
Leave your current water heater alone - that way your wife always has hot showers.
Add a second water heater in front on your water heater and this one runs off the solar dump load. It will always be cold water - and will heat the water up before going into your...
I just wanted to share a FRAUD Solar panel my friend was looking at getting on Amazon:
https://a.co/d/gA83egV
That would be a nice 300w panel - if it were true.
It looks good and the math is right Vmp & Imp.
But what caught my eye was it was approximately the same size as my 200w panels.
I...
That plan looks good - hopefully the Renogy inverter/charger works well for you… I don’t know anything about that AIO Inverter. From reading on this site Renogy brand seems to be either hit or miss. Some products are great others not-so-much.
On a boat I believe Triplex is recommended over...
I have a 600w array on a Victron mppt 100/30, (clips above 440w), it does work in that range, but it also tends to cause some issues with driving the charging voltage a bit high when clipping a lot - which causes that mppt to hit Absorbing and float - well before the other mppt does.
Because of...
When I was considering starting my Onan Generator with my Victron CCGX, I discovered a module that I almost purchased (I later decided to just start the generator manually - with the switch).

It was really interesting.
It seems to do all the things that would be...
I would get a Victron mppt 250/60 (or 250/70), and wire one of the arrays to it to just charge the batteries. That way both arrays are working at max performance.
If west array 4s2p into it.
If East array 3s2p.
Use the array that most closely matches your 120v usage go into the inverter...
Does your inverter have two separate mppt channels?
Do you have a battery? - if so the easiest thing may be to put one array just charging the battery with a separate mppt solar charge controller.
To figure out the penalty for combining the arrays we need to know for each array the panels:
Voc...
You still can do a ground array - get 4 panels hook them up in series, then connect to your ground mount mppt.
That’s if you decide you need more solar.
If you carefully select the ground mount panels so they work well with your roof mount array - yes you can. They will just be another parallel string. You will want the Vmp string voltage on the ground to be as close as possible to the Vmp string voltage of the roof array.
If you end up with...
I think everyone has the wrong idea about winter- if you are not getting enough sun in the winter to keep the battery full - go south - that’s what those big black tires on your MotorHome are for.
Winter in Arizona or Baja provides plenty of sun…
Oops - I think I missed the point😎.
In my...
You are looking for differences - are they all around 3.000v or are the all but one at 3.125v and one is at 2.850v.
Also on charging are they all close to the same 3.500v or all they all at 3.312v but one that is at 3.650v.
You are looking for the high and low and where most cells are at each...
