Remember you need to get the six panels for string1 and six panels for string2. If you decide to get more Sun Gold panels and put the Renogy panels onto their own Mppt SCC - go 2s2p and use a Victron 150/35 - they are like $184.

you have 12 panels… If you connect two strings 6s2p with those panels - what happens: String1 6s - (4 Renogy & 2 sun gold) Voc - 8x 41.25= 330v - you have plenty of room before 450v Volts - add the volts in series. 33*4 + 34.67*2 =201.34v Amps use lowest - 9.7a This string gives...

Try just plugging in array 2 by itself- does it run correctly? Verify you haven’t switched up the polarity…

Turn off all 120v breakers in your rig. (Maybe put the Multiplus in charger only mode). See if that helps… The issue is many devices may leak a couple a milivolts to ground and by themselves- no issues - so the manufacturers don’t care. But once the GFCI gets more than 5 milivolts going to...

You have the right idea - just using a wrong number. The Voc is just for figuring out the max voltage- in your case to absolutely stay below 450v. You need to apply to coldest temperature your area can have and adjust your voltage up. Note: often once you figure out what you are planning for...

Is your 5th wheel a 50a service or a 30amp service? If it’s a 50a get the Multiplus II 12/3000 120vx2. It will automatically take care of the dual phase/single phase issue. If it’s a 30a the original Multiplus will be a great deal.

Double check that your AIO can handle the amps from the array. Some AIO’s can’t handle a lot of amps (some can so check your specs).

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...

Welcome - watch out this hobby is addicting…😎

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). Atkinson electronics GSCM 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...
