I'm currently fitting large 435W on my RV. (82x 40 inches)
My idea is to fit the long edge (82 inches) across the roof and create a kind of spoiler hump in the front of the RV. (Primary use - is to clear above the vent)
This is recently done in Bus design and I saw it on some newer Class C...
Used large solar panels are reaching a point, that they are almost cheap as metal roofing.
So I'm thinking about combining those two pictures into once concept.
I wanted to build a Carport for my RV (20x26 ft) for a while, I figure - could I just use large panels to cover the structure...
Hello,
I replaced my lead batteries with a 100AH LFP and now need to upgrade the converter/charger with something which speaks lithium and I don't have to watch it.
Doing some research I found the Victron Energy Blue Smart IP22 30A - which has a lot of settings and looks like it should fit...
Hello,
On the topic of using space more efficient:
I found these article:

Currently planning a 7x14 or 7x16 Trailer - for towing behind my Class A RV to move to a new property.
There we are going to built a small house. During construction this trailer should also server as base of operations to support the whole thing.
Storing tools. Washing machine. Etc...
My Class A AGM batteries started to loose capacity especially when cold. So I got my self one of the newer group 24 LFPs.
Elefast 100ah with Bluetooth. My 12V system does only provide power to the lights, furnace etc. The 120V side is covered by a higher voltage solar system

Currently looking into moving to a new property (likely a blank Canvas)
Been doing a bunch of calculations on the power system, and since I'm getting all new everything.
I was wondering if instead of paying for a big inverter (AOI) - should just get all DC appliances and potentially a small...
Hello,
I found this video from off-grid garage reviewing a SEPLOS BMS.
It seems like it has a configurable active current limiting feature. He describes it as PWM circuit.
A battery with something like this should solve most alternator related concerns correct? Two main things kill...
I'm just getting a bunch of quotes for my house Solar System. Most of them are Enphase Microinverters, which are AC coupled.
Now my question, can you do this DC? I want to do build a DIY power-wall anyhow. Cost aside.
I have a weird roof shape with shading, so one or two MPPTs for 8KW...
Lets have a discussion here ;)
While I agree with many of @Will Prowse points in the Video about what a Truck should be used for.
Most people don't use them the intended way:

I'm currently researching to put on my Motorhome
Further I'm interested in putting Solar on my house.
Now on average I use the RV 60-90 days out of the year and when I'm not at home - I don't need lots of power.
So would be a waste to have a nice system on the RV and only use it that little...
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...
I got an RV with a 900W of Solar (2000w MPPT) and was thinking about building a Solar Carport (3-5kw) - to park the RV underneath.
https://understandsolar.com/solar-carport/
As soon as I get the RV parked I would like to switch to the stationery system.
Sure I could just have a few MC4...
This came out of the replies I got from my initial thread:
https://diysolarforum.com/threads/looking-for-all-in-one-recommendation-for-motorhome.20943/
Please take a look and let me know if I miss sized wires or fuses before I go on a shopping spree :P
For sale a AmpereTime 24V 100AH just about 1 year old. 5 year warranty. Had it in my RV - but upgraded to a 24V 200AH.
Didn't see many cycles, pulls full capacity according to my Growatt inverter. Using the RV maybe 50 days a year.

Hello,
my 2x 12V deepcycle batteries in my RV are just about to die. I got a 5500w Onan generator, which starts from those batteries.
The Amperetime and CHINS 100AH have those ratings:
Maximum Continuous Charging Current: 100A
Maximum Continuous Discharging Current: 100A
Maximum...
My Current Setup
So this is my current Van-Setup. Working very nice for 4 years now. Yes I got redundant PSW charge controllers (Amazon send me two when I ordered one), my panels are angled different direction and I got the feeling that with one controller per panel it's harvesting more.
The...
Hello Growatt users,
every supplier I look at has different dimensions of the SPF 3000TL LVM listed.
Everything from 23 inches x 17.3 inches x 9.2 inches to 17.9 x 17.8 x 5.1
Could some please shed light on this mystery and measure the width and depth of the Growatt? I'm working with a...
My RV has a old Onan 5500 Generator which it's on it's last leg. RV generators are rather expensive and put out 120V - 240V
So I was searching - could I replace the generator with a DC-Direct Gasoline generator?
V5 AutoGen 48v DC Generator Charger 70 amps maximum...

Hello,
I have a cargo trailer with many nice solar panels and I bought a EG4 PowerPro WallMount. Which will be connected to a 6000XP
Now need to figure out how to mount this heavy thing safely for one trip. The cargo trailer is used primary to support my move from one state to another and...
I got a Growatt spf 3000tl lvm-24p can handle 80A on 24V - which is right around 2000W of MPPT
How much panels can I safely?
The local 450W panels which are cheap are right around 50V OCV and 40V MPPT - the maximum input of the Growatt is 145V - so to play it safe from the voltage I...
Hello,
I'm following the 48V Blueprint:
https://www.mobile-solarpower.com/48v-complete-system-blueprint.html
I was just wondering - why is Will is using an external Busbar again? The internal busbar in the Server rack is pretty thick.
Just came up with this design:

I was wondering - my new 86 inch x 41 big panels have only 4 holes in the back for mounting.
While some smaller panels I have - had 6 or 8 holes
Are 4 bolt sufficient?
I can understand with front clamp mounts - yes 4 bolts are usually ok. But with the thin aluminum frame at the back - even...
Looking for my RV - I can only fit a Group 24 Size. The newer Minis would fit as well.
I need a battery which can still discharge when cold - but stops charging when getting frozen.
It is really just running lights and the furnace. No need to get fancy ;) I got a 10kWh of batteries on 24V...
I got a 6V battery systems in my Golf Carts (at work) which served me fine for years. They have 6 batteries (36V) or 8 Batteries (48v)
So I noticed that always the first battery in the string on one (sometimes positive, sometimes negative) side goes out of balance - even with equalizing...
I have a Growatt SPF 3000TL LVM and installed it in a RV. It's working great, aside from one little issue.
Input GFCI trips occasionally.
When I'm at home I plug in the RV with an adapter into an exterior 20A outlet (reduced the charging rate) which is protected by an GFCI outlet.
After...
Fort Myers checking in - thankfully we left and are safe but we want to get back at some point. So usually I use this setup for camping and not live full time.
Now we might be forced to RV living for the foreseeable future, since the power grid is destroyed down here So my question is - how...
Hello,
I got an RV with 2x 72V 435W Panels and found space to add another 445W panel.
Constrains:
Unable to find another of the 72V panels - those are like unicorns.
MPPT max voltage of 150V and I don't necessary want to add another MPPT controller since my Growatt has plenty of capacity...
