I highly recommend Victron for everything except batteries. But especially for the Multiplus 12/3000. That is an awesome unit. I have been using it since 2018 - full-time 24/7 for 3 years. It’s not just the customer service from Renogy, they buy other companies stuff and put their label on it...

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...

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...

It has Dicor on it - I think this photo was taken towards the end of the project- before that step.

I have been helping my Brother-in-Law design his system. We went the same way using the PowerIn’s as the Main Bus Bar. Here is a photo in the middle of construction (actually at a day’s end). The PowerIn on the left will connect to his three Lithium batteries. The switch and BMV712 in...

I don’t worry about theft because if you steal my Starlink you can’t do anything with it - cannot be reused unless the owner transfers the rights via the app. That kills the stolen market.

Some of the BMS built in counters are not known to be accurate. You may want to get a Victron Smartshunt (or Bmv712) to accurately measure the current flowing into and out of the battery- $112 Also if your cells have become unbalanced, you could be shutting down due to a low cell voltage...

Mine is the Gen2 so it points itself. I got a FlagPoleBuddy system and usually attach it to my ladder w/2 4’ poles (starts out at about 7’ - so it is about 15’ up there) - I have another 2 poles to get it much higher to help w/trees if needed. I have the base and have a 150’ cable- sometimes...

With Starlink it varies- but it is all “fast enough”. I just tested as I was writing this In Arkansas (11pm) and it was the slowest I have seen in a long time 26Mbps down and 15 up. Yesterday 10am, I got 148Mbps down and 18 up. Same spot. A few months ago we were in Baja and the speed really...

I think you can zoom on my dad’s brackets in the photo. He cut two 3” pieces. One he bolted onto the bottom of the solar panel frame, the other was screwed into the roof. Then he bolted the two brackets together. It made a “Z” shape (except 90 degree bend instead of 45). I remember...

As a full-time RVer - for us Starlink has been awesome! $150/mo (roam) and I can get signal as long as I don’t have too many trees above me. We boondock a lot and often in areas that don’t have any signal.

I used 2” “L” angle stock .125” (from On Line Metals). I made mine 6” long. I used eight prices per 200w panel - bolted four to the corners of the panel and the other four were attached to my Fiberglass roof - VHB Tape, plus a roof screw - Dicore over everything. Mine are in a “C” shape. A...

Thanks for the catch… typo between the brain and the finger…. I fixed the above statement to be correct. 😎

Ok back to interesting problems of mis-matched panels… One other idea. Add a mppt. Mppt#1 100/50: put the two100w panels in parallel- then put them in series with the 200w panel. Design so if you ground mount any they go on this array. Mppt#2 put right side 55w + 35w panels in parallel… put...

I used a Victron Multiplus in my MotorHome - it is an inverter/charger and works VERY well. Upstream of the inverter is a transfer switch to switch between grid & generator. One very important thing to check is that the inverter is handling the N-G bonds correctly (Neutral-Ground Bonds). You...

Wow 4 different panels… with 7 panels in total… 1 200w 2 100w 2 55w 2 35w This will be a fun problem. To get started we need to know for each panel the following specs. Voc Vmp Imp And your battery voltage and type.(example - 12v LiFePo4). Also, have you already purchased any Solar Charge...

One issue you need to solve is your N-G bond. (Neutral-Ground Bond). This unit doesn’t help. When on inverter your inverter needs to supply the N-G. When on generator, the generator needs to supply the N-G bond. When on Grid, the grid will supply the bond. You CANNOT have more than one N-G...
