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...

@Pappion I did what you say...but I have a 30 amp charger tied into the positive bus bar (not shown on my drawing). It blew the fuse..although I only had a 20 amp fuse in the short wire. In order to use 30 amp. do I just need to upgrade the short wire (and fuse) I moved to say 8 or 6...

@Pappion Good points. So I would tie in the 10AWG wire (to the bus bar) on the output side of the Class T, but before the inverter switch? TY

That's a good thought about keeping a LA battery for the brakes. When I moved my batteries inside when I went with lithium. One thing I hated when they were on the tongue was if you turned the battery switch off, it also turned the power to the e-brakes off. So if you mistakenly left your...

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...

tks...I'm a bit fuzzy what you mean by "Green should be moved" You mean replace all the blade type fuses?

Hi, I was able to check voltage drops. Do these numbers make sense? This was before doing any changes or inspection of the connection points. Top or first number was inverter on, but no load. Second or bottom number is inverter on with microwave (900W) heating water Circled number was...

Hi, This is the busbar. 400 amp solid copper https://www.amazon.com/gp/product/B08JKZ4GCN/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

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...

Got..it may take me a few days..I'm going camping solo next weekend and will have time to check all connectons. The voltage drop just confused me a bit when checking the negative. So you just check the current between two points independant of positive or negative. TY

Ca Can you please provide me the technique to check voltagre drop so I do it correctly.

The fuse is 225A. I will check all the connections and confirm no washer under the lugs.

12V; Batteriesi parallel

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

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 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...

No it does not connect

Hi, I have a new IP22 victron charger. When I plug it in to AC voltage, there are no lights nor 12V on the output. I've checked the fuse and it's good. Any resets or anything else to check or is it defective? Thank you

Hi, I have almost an indentical set up. How do you plan to connect the charger to the transfer switch? Cut off plug and connect directly to charger or wire in a female plug to the transfer switch and plug the charger? What brand charger Also if yiu disconnect the charger/converter...

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.

Hi, So, I'm clear you remove the wires circled in the picture and connect the IP22 output there? That will charge the batteries and run the 12V circuits? Correct Tks

Hi @turkington Old thread but have a question. When you disconnected the AC input, didn't that also remove power to the 12V circuits since it's a combo converter/charger that cna't be seperated.

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...

No it's not. The converter/charger is wired in the transfer switch to a contact to only be powered when on shore power. So the converter/charger will continue to run (with fan) because it can not get to the float votage for Li batteries? (It's a converter/charger for lead acid batteries, I...

Hi, The Class T is only 6" from the battery. It's very close. Someone else on this forum told me that was acceptable.

Hi, Not shown in diagram, but the 12 V black (actually white wires) go to the box shown on the right of the diagram listed as "12V ground bar for 12V systems" which is wired to the neg. bus bar and then to the shunt. So all the 12V loads go to the shunt via the ground bar shown on the diagram.

Hi, An update. I've realized that when the battery switch (red switch in diagram ) going to the WFCO is off, the smart shunt shunt shows almost no power draw (left below) , which makes sense , but when the battery switch is on, the smart shunt shows 6.03 A /81W and the fan for the...

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...

I do have an inverter, but it's off.

Hi, This is how it's wired.

Hi, Quick smart shunt question. I have my system on shore power. When I turn on devices, the smart shunt shows an increase in power and amps. Even though it's not running on battery only, is that how it works (reconize the loads)? Just making sure I have things wired ok. I am certain it's...

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

Hi, Can an external solar port that is wired to the batteries also be used to hook up a battery charger ? My battery charge (Noco 5 amp) has an adpater that can be plugged into the SAE/Zamp plug. The wiring is 10 AWG. My batteries are inside, somewhat hidden and difficult to directly...

Hi, I have a small trailer and have an inverter and transfer switch installed. Here's a picture. The transfer switch has input from 120 and inverter and output to the fuse/breaker box. The transfer switch allows all the 120 outlets and devices to work, using the inverter, when running...

tks..The fuse holder shown between the SAE plug and the bus bar is actually right at the plug. Would a fuse be required between the SAE plug and the charger? Is that what you are saying?
