Thank you, I'm in the middle of installing a 2000W inverter, 2 x 105 Ah battery and a transfer switch in a small travel trailer. I have a 250 amp Class T. This all becomes confusing as there are so many set ups I see while trying to follow these threads. Sorry to hijack this thread and...

The circled wires (red and white) in the photo go to the charge/converter. That photo is from a WFCO video that is taken apart. There is a red wire on the #6 fuse that goes to the battery bank.

No it does not connect

@Charleswgibbs Yes, the external solar plug is for a second portable solar panel with a controller. I can't explain why is wired this way. It is the way the RV came to me. Attach is the switch. Yes it turns all loads and power off inside the RV. Maybe the negatives are not wired to the...

I have a small teardrop with a 8735P converter. I'm almost sure the wire coming out from it is only 10 AWG..but I'll double check. That is why I went with 10 AWG. One other question. (sorry), I have a victron IP22 charger wired to my busbars (with 6 AWG wire). Should I have fuse protection...

tks..good catch. I missed that.

Hi, I am far from an expert, but how did you come up with a 150A fuse for your inverter? The sizing goes 2,200/0.9 (assume90% efficency)= 2444 W; Divide by battery voltage; = 203A ; X 1.25 Safety Factor = 254A I guess you say your max load is 330W? Then why such a large inverter? What...

Hi, I'm also new trying to follow and understand..a couple of questions: 1. So I'm clear..(which I'm not) if a battery BMS has short circuit protection, no addtional fuse is required for the battery itself? Correct? Only the one fuse protection is required for the inverter. 2. Is there...

Hi, I have a small camper with OEM WFCO 8735P (non lithium) and inverter, transfer switch (GoPower T-30). I currently have the AC wires of the WFCO converter/charger wired into the transfer switch so it only charges the battery when on shore power. I want to upgrade to a stand alone...

@Charleswgibbs Thank you. I just figured out how to remove the battery switch and as you say, only the two positives are tied to the switch. The negatives looked like they ran into it, but actually go behind and into the trailer. So do you recommend to move one of the wires of the external...

Hi, Do you mean both postive terminals of each battery? The Class T fuse is to protect the dedicated inverter circuit. Everything going to the pos. bus bar is 30 amps or less on 10 AWG wire only and is protected by a 30 A fuse in between the battery and bus bar (shown). The top left is a...

Hi, When checking voltage drop is it better to have a larger load like the a microwave or will a smaller load work. Asking because when running the microwave, it obviously consumes much more battery and will you may notice the change in voltage more due to consumption rather than an actual...

Geez..sorry ...my why question was just to understand your approach. Never said anything was wrong. Just offered suggestions what I've learned over the last few months. Maybe you had reasons...like 1. I got it off another set up, 2. Someone else suggested it to me or I just guessed. Any...

Yes, I'm 100% sure it goes directly to the battery (I wired it). I also have checked the ploarity and know which side of the plug is positiver and negative. Thank you

I was keeping the 30 amp circuit seperate from the higher load inverter circuit. If I move it to the other side of the Class T do I keep the 30 amp fuse? I'm not sure what moving after the class T accomplishes other than not having directly connected tot he battery. That circuit does not need...

Hi, I have a similar set up. 1. Just wondering why you selected 2/0 cable from the switch to the Safety Hub. I do see you have a question mark. I'm using cable based on maximum fuse in my power center. 2. Why are you connecting your inverter through the switch. Why not from the Class T...

Hi, New lithium battery owner here. A few basic questions that I can't seem to find summarized. 1. When hooked up to shore power, say for mutliple days, should the battery converter/charger remain on charging the battery or turned off? 2. Same for solar panel chargers? 3. If not used for...

Hi , I recently installed 2 x 100 Lithium battery's and an 2000 inverter. I used 2/0 AWG wiring. While running the 900W microwave, I checked my wiring and some seemed a bit warm...not hot. I want to check all my connections. Besides correct torque values, is there any other good practices...

Lithium iron phosphate

Hi, A picture of my wiring layout? The warmest areas are the yellow circle and between the Class T and switch. Thank you

Hi, I have a couple of questions and also looking for any feedback on my new lithium battery and inverter install in a camper van with existing solar. I'm moving the lithium batteries inside but trying to preserve the OEM battery wiring on the outside (where the lead batteries where located)...

All the large 2/0 wire are single lug per stud. I can take pictures, but what is recommendedso I can first check. Is it : Busbar/washer/lock washer/bolt. TY

12V; Batteriesi parallel

tks, I know for wet cells batteries it will go into float, but not sure if it will for lithium. It is a WFCO8735. It's on my next thing to upgrade, but it will be a few months.
