I run lithoum house batteries and agm starter My trial and error has taught me this... No lithium Iron is drop in on a boat, and almost none can be used as a starting battery, those that can are super expensive. Fuses are a must 3 choices: Victron DC-DC charger is the best Renogy 20A & 40A...

I've seen 10bb and 9bb panels 10 bus bar panels state they are 30% smaller than standard. I have 1 9bb panel it's either newpowa or bougeRV can't remember but it is smaller and puts out the same wattage as the panel it replaced. I also have a new mega watt panel by rich solar it's only 13"...

Been using only Ancor brand wire and lugs. All tinned copper. Off-brand that looks identical doesn't hold up as well to UV. Ancor literally the only wire I will ever buy. New silicone wire has been gaining traction though but its still all China stuff, I don't trust it just yet but it will...

Sorry I left out a couple words: my trucks aux wire will power ONLY the charger, the 100Ah trailer battery will power the inverter. Sunsurfer - My truck has the highest rating for an aux wire. 40A and its a 10ga wire that goes wight to the side nut on the battery, that fuse is called STUD...

Thank you guys much appreciated! So I will not ground the inverter to the trailer either and I'll bump it up to 125A fuse. I use terminal fuses. Im like obsessed with them. I have them on every single battery. In my mind there's no closer you can get than to right on the battery. I have...

I usually do things the best way I can BUT with this build, I'm doing it the dumdum way. Think it's ok? I'm partially disabled and I need a way to help me with loading and unloading the boat from the trailer. I am installing an electric winch and an electric boat jack on my boat trailer. Also...

Starting to see more and more YT videos saying to use a LiFePo4 "Starter Battery" as a drop-in LA replacement and you're good. I even wrote a comment on one video that the system still needs an alternator protector like the Balmar APM-12 AND a smart alternator or a regulator but that it was...

If for camping check out the voyager controller, one of my solar systems is on a boat and I couldn't use the rover because of the moisture but the voyager is still going strong 1 year later dealing with highly corrosive seasonal.

Victron taste with Renogy pockets. I know you're not going to want to hear this but you're making a mountain out of a molehill and this is my open letter/ discussion to you! 1. Renogy is not a manufacturer. They are a retailer and in my eyes a marketing agency. The products you are...

I provided the wrong guide link. This is the correct link. https://diysolarforum.com/resources/wiring-unlimited.2/ It's the best guide I've seen by far. Will has a book also, it can be found on Amazon, "Mobile Solar Power Made Easy" I have that also and having it is a nice way to support him...

This guide book is the best tool I've ever found. I printed it out and keep it with my generator. https://diysolarforum.com/resources/wiring-unlimited.2/ Should definitely check it out. I printed out and keep in that book the wire chart I posted and this chart for fuses. With those 3 onhand...

Maybe the wire ga in his kits are all super oversized or he only sells 48V kits. That is the only way that you wouldn't see loss. Maybe he uses all 2ga wire in his kits. You could run 20 amps through 2ga and see basically no loss at 100 ft. I doubt that's the case though. What gauge wire is he...

I cant tell if you're being sarcastic orrr I'm an idiot. You have 540 posts and I have like 4 so I assume sarcasm or something went over my head. My electrical knowledge is like a 5 out of 10. So at the threat of sounding stupid... and since other people in this post also are asking what the...

I have not heard that using 4 batteries is no longer the recommendation. I don't see why not. My set up is 4 100ah batteries, I'm working with what I got and that's what actually fits the best also. 200ah batteries did not fit in the space and all my consumption calculations are based on 400ah...

Hi guys I have 4 batteries, due to space constraints 3 batteries are on the bottom level and 1 is on top of the 3. Instead of hooking up all 4 in standard parallel fashion couldn't I benefit from hooking the bottom 3 in standard fashion, then hook the 3rd battery diagonally to those 3 and...

Hi guys, has anyone had this issue before with the Renogy app. The app is showing 20-30 watts 2-4 amps LESS than actual power. For example my panels right now are pulling 245 watts. My watter meter shows 245 18amps, my renogy shunt shows 245 18 amps, the renogy charge controllwr shows 16...

I'll send a pic of the sides, that's where the DC-DC is (left side, not left back) Its 12v. Batteries are 100a total if 1 internal bms failed. The AC-DC is only 10a The DC-DC charger is 40a (installed only as backup to solar) DC-DC charger has 50a in and 60a fuse to battery. (Both are out...

Hi all, I have tried to search this in the forum and on the web and there's no posts on this. My Renogy Battery Monitor with 500A smart shunt has a parameter setting called Battery Attenuation ratio. It's set to 00.000 it's literally the only thing left for me to set in my whole system before...

HI guys I wanted to compile this little bit of data in one place. When I first set up my Renogy Rover Charge controller I had a difficult time finding this and it was spread out through multiple different places so here it is: So you've just set up your new Renogy, Rich Solar, Weize, or other...

I run 4 of the 100Ah weize batteries 1 10Ah and 1 20Ah batteries from them. So far so good on all 6 batteries. They sell versions in 10ah, 12ah, 18, 20, 55ah, 100ah, AND NOW also 200ah as well! If you buy on Amazon they are sold by Powermall and BLT HARD and now XI Run. These are all the...

Thanks for your replies guys. The manufacturer did get back to me and they said they changed the studs and that's the only change. That the new inverters all use the 1/4" studs. I don't know if I believe that or rather it was hit with stock issues like us all, but thats what they said. I...

I just wanted to add this converter to the options also. I use these for one of my cameras. I actually like the option of just using a 12volt car charger like someone posted. Those usually have just the right voltage. Some cameras and devices will say a message like use the included AC...

Thanks for the answer. I guess I'll just keep it then and not return or exchange. I will be extra careful though. A 4/0 ga wire I feel needs to be careful on a 1/4" I would think, maybe I'll add a wire brace to take any strain off the bolt. Then I guess I'll have the most contact surface and...

Woah! Thank you! Awesome guide. Thanks so much.

Oh last Q. I have 2 more batteries on the way to give 400 amp hours total of LI. When you connect 4 batteries in Parallel you connect to the system in one of the middle 2 batteries? Is that correct? They all have internal BMS's.

Thanks for all the replies and help so far. Everything is basically wired up now. I have not tested all components yet though. I just want to make sure... My 10Amp AC-DC charger is hooked in to my neg and pos bus bars. When I turn on the charger the current wont flow to my solar panels or...

Quick question. This is my second GoWise Pure Sinewave inverter. My old 1,000 Watt came with 3/8" terminal post to connect to. My brand new 3,000 GoWise inverter came with 1/4" posts. The photos of the inverter all show what looks like 3/8" and on Amazon, I saw someone else ask if the...

UPDATE: So I cut and shortened both the AC and the DC end of the cables. On the DC end, I went with the assumption that it was a temp sensor and not a voltage or resistance sensor since it stops where the Black plastic NOCO thing is. So I assume that its in there whatever it is. it was 28 ga...

UPDATE: Hey guys, well I screwed myself. Could this be the reason why both leads had a fuse? So hidden inside the cable coming from the NOCO charge are 2 super tiny maybe 26ga wires. I cut the wire and now I'm stuck at a standpoint. NOCO won't answer what they are for. They say...

Thank you guys so much for the help. You have really helped me to better understand everything and keep it safer too. My last question is how do you know when you need a fuse on both the positive AND negative wire? I always thought you only needed a fuse on the + wire, but my NOCO AC-DC charger...

Ah, gotcha. I was putting in a 300A Mega. I have a pack of 250's though. I will swap it out and put in the 250A until I replace the 2/0 wires for 4/0. Thank you for those suggestions. I tested the inverter when I got it with an 1800 watt blowdryer to make sure I didn't have the same issue...

My fuse block/bus bar is a blue sea systems 125A marine bus. It says on the package max recommended max fuse is 30A. Could I Have the wires coming from my 40A Solar Charge Controller go to the bus instead of the Shunt off the battery. It is a 40A fuse needed, and doing my calculation for max...

Haha good eye. Yes the wire dangling from the inverter is the crap wire it came with. Its just there now for measuring purposes. These are the wires I am using. I got 2/0 because I have no plan to every actually use 3,000 watts. I only got this 3,000 watt inverter because some reviews said...

Hi guys, brand new here, long-time lurker. I am building a DIY gen and had a quick question. I am trying to keep my install cabinet as clean and simple as possible. I am wiring up an AC-DC 10amp NOCO charger to the system for when the unit is in storage. Can I wire this directly to the...
