I have yet to connect the Multiplus Aux Charge port to my standalone 12v battery that is used to start the generator and run the tongue jack. Documentation on the Aux port is rather sparse. When does the Aux battery get charged? Is it only when the Multiplus would also be charging the main...

For a little bit of extra protection against accidental contact, I drew up a bus bar cover and a friend of mine created it on his 3D printer. The covers were 12" long and I cut them to fit. He gave me three covers. Before installation of the covers. New covers installed. Here's what the...

Not quite clickbait with the title, but it's an interesting issue that I ran into with an "Operator Error" solution. I have a Victron SmartSolar 100/20-48 MPPT and two Victron 100/50 SmartSolar 100/50 MPPT. All three were networked using my BMV-712. The two 100/50 were wired into the Cerbo...

There's milk crate builds and suitcase builds, mine is a board build. I'll be using this for remote tent camping - in places that I'm not willing to take my RV trailer - mostly for powering Starlink and my laptop so I can work remote if I have to. I'll test it at home to see if it will power a...

In 2020 I purchased four Mission Solar 320 watt panels over the phone, showed up 30 minutes later with my pickup and was gone five minutes after that. They loaded the panels into my truck on a pallet. It was a very easy transaction. I paid less - for the same panels - than another local...

Recently I noticed that the email notifications that I receive no longer have the content of the post. It's now just the title of the thread and a link to open it in the browser. I don't see a way to get that back in my Account Preferences. My ISP seems to deliver only half the email...

I picked up four 280 watt Solar World panels from Marion on 08/27/2022. He operates out of an established warehouse/business building located near Smith and Monaco (north Denver). He isn't some guy that is peddling panels in a parking lot. I found him through a listing on Craig's List. He...

I think I found Will's long lost brother. This guy has similar energy levels, but for food instead of DIY solar.

If I set the AC input amp limit on my Multiplus 12/3000, it seems to be using less than the limit and then making up the difference with Power Assist. For example, I connected to a 15 amp shore power circuit at home so I set the Multiplus to 15 amps. What I see on my Cerbo GX/Touch 50 screen...

I'm planning to add air flow to my battery and inverter compartments. I've been poking around on the CoolerGuys website and ran up against a 13.8 volt limit on most of their fans - at least in the sizes I need. Some fans are listed as just 12 volt with no range. I asked them about the upper...

I've been away from the forums for a few days, so maybe it's just me having a senior moment. It used to be that I would read new posts in the specific subforums I'm interested in. Then I would mark the entire forum "Read" when I was done by clicking a link on the banner at the top of the page...

I've been noticing that quite a few threads that I'm following are not sending me email notification when there are updates to the thread. I've checked my junk/spam folders and nothing shows there. I do get notifications for some threads. After reading the forum I mark all threads as read...

Any recommendations on how to keep Victron VE.Direct cables from coming loose? I'm using them between my Cerbo GX and two MPPT as well as a BMV-712. The cables seem to disconnect fairly easy. I'm going to add some strain relief that I hope helps but securing the cable to the underside of the...

Not an "up in smoke" result but I said "WTF?" a lot. In rewiring my system for a new Multiplus inverter/charger I managed to switch the positive and negative cables at the inverter. Beats my why I did that, it's clearly labeled. In my defense, it's clearly labeled until you put cables on the...

The first iteration of my system used all 2/0 cabling between the big components such as between the battery and the shunt and fuse. I'm in the process of rearranging my system to make way for an inverter/charger upgrade. In doing so, I decided to ditch the 2/0 cable where I could and use...

+A = B = C- The above battery wiring configuration is what we often see for lead acid batteries. It's simple, but not optimal. For a LiFePO4 battery, it's my theory that this is a bad configuration that could lead to undercharging. If the BMS in battery A detects that the voltage has reached...

While researching another topic, I came across this webpage that covers how to connect bus bars. The key detail I took from the article is that the surface contact between two connecting bus bars needs to be five times the cross section of the bus bar...

I'm rearranging the components in my system and replacing a couple components. The four stud bus bars are being replaced with eight stud bus bars with much higher amperage capacity. A new PSW inverter/charger is going in to replace the separate MSW inverter and the AC-DC converter. Many of...

I have a Victron Multiplus 12/3000 on order that will be installed in my RV trailer that already has Victron MPPT controllers and a BMV-712. The Multiplus specification says it's 93% efficient, so I'm using 1.07 in my calculations. I'm conservatively using 12 volts in my calculations even...

My plan is to upgrade my existing 1000 watt Xantrex MSW inverter to the Victron Multiplus 12/3000/120 (2400 watts). I already have the Victron BMV-712 (with display) and two Victron MPPT 100/50 solar charge controllers installed. If I add the Cerbo GX and the GX Touch 50, how does that...

Not sure where to post this as it's about mini-splits in general. It doesn't matter what you mount it to (RV, building, etc). How flexible are the coolant lines between the inside and outside units of the mini-split? The reason I'm asking is that I'm getting ready to rebuild the entire front...

I'm considering building a 20 Ah 8s 24v battery. This is for an electric lawnmower. Space is very limited in the battery box. Should I get the Overkill Solar/JBD 8s BMS or is there another BMS that is closer to the 20Ah rating of the battery that I should use instead? The Overkill Solar BMS...

Think the price of new equipment is bad? Used is just as bad. I'm looking for a remote control panel for an older Xantrex inverter. Xantrex discontinued the inverter some time ago and inventory of the remote control panel dried up over the past few months. It was suggested that I try the...

Howdy from rainy Arizona. New tires were put on my truck this morning in Las Vegas. Discount Tire put on Goodyear Wrangler Adventurers (same as the OEM tire I had from the factory), replacing the Michelin LTX. It's a very different ride now. The truck behaves well and isn't all over the road...

Is it just me or have there been a ton of problems with Daly BMS lately? Problems with Electrodacus: Zero. But maybe the issues are being posted elsewhere? Problems with Overkill Solar BMS: Minimal. I separate out the OKS BMS from the JBD BMS because OKS carries a subset of what is available...

While it's not in the official Code of Conduct, the issue of posting IN ALL CAPS is flaring up in a current thread. In forums, it's often an unwritten rule that you simply don't post in all caps. My dad does it all the time in email and even he can't explain why he does it. The current Code...

I know there are a few forum members that have said they drive a Ford truck to pull an RV trailer or to haul a slide-in camper. Here's your chance to check in and post a picture.

A few days ago I used my new Dewalt cordless heat gun. When I did my solar/battery install last fall in the RV trailer, the heat shrink tubing for the 2/0 cable was on backorder. This cleans up that install and puts it to bed. For those of us with an RV, we can't always work on them at home or...

I have a two-pole breaker that is rated for 20 amps on each breaker. At the outlet, is that a 40 amp circuit? Or is it a 20 amp circuit? This question is not related to PV. It's for an outlet in my garage. No PV/battery/inverter in my house.

First of all, this is not a complaint in relation to anything going on here. It's more of a future concern since we don't have threads old enough to be considered "old" or at the very least ancient history. A forums that closes threads that are older than X number of months, does, in my...

I'm looking for a new source for project metal, specifically aluminum. I was using OnlineMetals.com but their metal prices are high and their shipping is very uncompetitive. For one project I had to verify the shipping price with a customer service representative. It was so high I thought it...

Anybody else "attending" the conference? It starts this morning. I'm listening in on just a few sessions. Link for more info: https://alte-january-2021-virtual-solar-conference.heysummit.com/
