r/Victron

Hey all, I’ve been messing around with a small always-on camper/RV status display because I got tired of opening different apps just to check the basics.

The goal is to put stuff like Victron battery/solar data, Mopeka propane levels, temps, and other wireless sensor data on one screen so you don’t have to keep jumping between apps. Not trying to replace those apps. More like a simple heads-up display that puts everything in one place.

Right now it’s running on one of those cheap little touchscreen dev boards you can get on Amazon for about $20. I’d love feedback on the idea from people here, especially if you already use Victron and/or Mopeka in a camper, van, or off-grid setup.

Also, if anyone wants to beta test it on your own hardware and is comfortable flashing firmware, reach out. Mostly just trying to figure out if this is actually useful or if people prefer their apps.

I have a Multiplus-II 48/8000 here in the UK running in ESS mode, connected to a pair of Fogstar 16.1kWh batteries. The system has been running for 6+ months with no issues.

Last night at 23:30, the system flipped over to charge during the nightly off peak rate, battery SOC went from 51 -> 53% and a few minutes later, stopped charging. Since then, the MP is showing 'inverting' in the Cerbo UI, it's showing voltage on AC Out and the ET112 meter is connected and showing Grid usage.

There's no errors that appear on the Cerbo or in VRM online, no configuration changes have been made recently. However the MP is not showing 'Mains On'.

I've tried a full power cycle of both the AC and DC side to no avail. I'm stuck for ideas on where to start troubleshooting,

Can Cerbo GX see other Victron devices via Bluetooth, such as Orion, Battery sensors, etc.?

Hi, I setup two Victron Orion XS 50 amp chargers onto one big 280AH lifepo4. According to specs on the battery they say it can handle up to 160 amps of charging. My alternator and engine bay wiring upgraded to 240 amp high output. All wiring in system carefully calculated to the correct gauge and fusing. However...! the chargers max out around 60 amps total and refuse to go higher. I can have one running at 50, the other at 10. Both at 30, etc, etc... total maxed out at 60 amps no matter what. They just wont go any higher. I dont plan on pushing the full 100 amps as it would stress my alternator too much. Ideally I could get up to 70 or 80 total. Ive heard of others having a similar issue with two of these chargers in tandem.​ Has anyone figured out how to fix this? Settings in the charger? Maybe my battery is just taking all that it possibly can and refuses to charge higher? Thanks, any input appreciated.

I've put this together today after putting it off for weeks. I've been sent the blue trunking too but I think it looks cleaner without it. Is it ok to have the cables overlapping like this?

Other than that does it look right?

Thanks in advance.

Things that need adding:

240V socket from consumer unit
Shore power from consumer unit
12V accesories from fuse box
Cables from Orion Tr Smart DC - DC charger to the van battery
Leisure batteries (the cables are just placed for illustration purposes.

Hey guys, I recently put a Victron MPPT and a SmartShunt in my van. Is there a simple dashboard app? I don't want to invest in a Cerbo and all these fancy things. I just need a simple dashboard and any help is appreciated.

What's the best way to charge a 24v bank and a smaller 12v bank off the same solar array? I've read that you should only have 1 mppt controller per array, so 2 mppt chargers won't work.

I'm looking at the DC-DC chargers for the 12v bank feeding off the 24v bank but they seem to be geared towards alternators, and I don't know how the mppt would like it.

I’m looking for thoughts on a soup to nuts system in northern Maine grid tied.
This would be the biggest I’ve attempted.

The Victron SuperCycle AGM batteries were marketed as being an AGM with better depth of discharge performance, but it seems that they've mostly been discontinued. Does anyone have any direct experience with them, and were they not as good as advertised?

Hello All,

Probably a dumb question, but I have a Quattro II 2x120V installed in my motorhome. I initially set it up as a basic system with 4-100AH batteries, generator and shore connections. For that, it works flawlessly. My question is, can the Quattro be set to use battery power (inverting) to a certain charge state, before it would automatically kick back over to charge/passthrough? I added a solar MPPT 100/50 and a couple panels to the system, but when plugged in at my house, the solar of course doesn't help much as the Quattro keeps the batteries topped up.

I know it's dumb, but I like to keep my mini split on (or furnace) to keep a bare minimum climate control in there (80 in summer, 35-45 in winter) just to control some of the major temperature swings we see here (-30f to 95+). I typically have the RV outside, and the solar would keep up with it most of the times. But, with a small setup, one cloudy day can send it down quick. I would like to be able to have the system pull from the batteries until a certain percentage (50%? whatever might be recommended) and then switch back to charging without having to monitor constantly.

Overall, it's not a big deal. It amounts to 2-4 KWh per day, only about $14 per month. It's probably more for proof of concept, as well as feeling like an absolute waste of resources to heat and cool a spare home. The rest of the setup is pretty automatic, when traveling I run on full inverter mode. I have the Orion 12/12-50 which keeps on top of all consumption (Air, AC fridge, etc). I added the solar to assist the alternator charger, and maybe reduce the load on the alternator. I bought the kit to auto start the generator if the battery level gets too low, but I have not installed that yet. I meant for that to be used when overnight sleeping on our trips (have had a couple nights that the batteries died overnight.)

Thanks!

Has anyone been successful in connecting the two? I assume mine doesn't work because everything is setup through the VRM.

TLDR; can the multiplus II inverter be programmed for battery configs and AC input limits/options out of box using the Cerbo GX instead of having to use the usb programming cable?

Hi guys!

New installation here, helping a friend. So far I’ve only received and tested a multiplus II 3000w 48v unit along with a 150 | 70 charge controller for a 48v 4x 12v series LFP battery setup.

At the off-grid cabin, we fired up the Multiplus II and ran several tests. Appliances worked well running from the battery bank. Inverter portion was A+.

The manual reads that the DC side only supplies (charges) the battery bank at up to 35A (1680 watt). We attempted to run the AC input from the 3800W generator. We plugged into the 30 connector. AC input light illuminated, charging began and roughly 1700w was being applied to the battery bank. The inverter would then disable charging after 20 seconds or so, it’d automatically wait and retry after another 20 seconds and repeat this same cycle. I’m assuming the inverter is detecting an input discrepancy that it’s unhappy with.

Being totally new to the multiplus II but familiar many other victrion products, I had no idea it didn’t have Bluetooth built in. My xantrex XC2000 had that. No huge deal, should have read the installation guides, eh? Lol.

Friend plans on ordering a Cerbo GX for remote monitoring/controls, etc. Do I absolutely have to have the Victron usb adapter to program this inverter or will the Cerbo device give me proper ability to configure the unit? EDIT: and can this all done via Bluetooth without requirement of the touch screen hardware?

Unfortunately; the charge controller arrived DOA. Pv input is a dead short. Tested pv input wiring at 60-70v before connecting and proper polarity. Turning on PV breaker immediately kicks pv breaker even with charging mode disabled and trying to limit amperage in the settings. Will get a replacement on the way.

Hi guys, i have an off grid solar system in my garage, with 2x 20v 100w panels wired in parallel, and in my work i was offered a 50v 450w panel that would be otherwise thrown in the trash, could i wire it together with my panels? Im new to this.. thank you guys✌️
