Hello, I'm trying to figure out chassis grounding for my RV. I understand that I need to either find an existing screw or drill one and remove paint at contact points. What I'm unsure of is how many components can be grounded in one place or how many amps or volts one point of contact can...

Actually, it might just be for ac ground. To install a dc ground bar is it as simple as scraping off the paint on the chassis, drilling a screw through the frame, and running a wire back to a ground bar that I can use to ground dc components? If my battery doesn't have an external ground on it...

Hello, I'm figuring out the whole grounding thing but I'm a little unsure whether to ground my Sok 206 ah battery. I would prefer to even if it is overkill but I'm not sure what AWG wire to use, would I need something rated for at least 206 amps? I'm also wondering if my solar installation would...

Hello, I have 6 100 watt HQST panels on my roof that will be in 2s3p going into a 40a epever SCC and I'm trying to figure out the grounding issue but I've found a lot of contradicting information. What AWG and type of wire do I need? Will I need grounding lugs? If I install on aluminum rails or...

How would I go about keeping the original wire hooked up and connecting a new wire for the lithium battery? I know that the WFCO 8955 has 2 battery inputs but I don't know what they are for. Would I need to add a fused but bar or something like that? (One thing to consider is cutting the 12V...

I have purchased a 100ah Ampere Time battery and will be installing it inside my travel trailer in the dinette seat storage, it is directly across from the power distribution center and protected from the elements. I have called WFCO and they agreed that simply running a new 6awg line to the...

Do I need a mega fuse at the battery? If so how do I size it? I won't use an inverter but I plan to use a small fuse box to run a few pc fans to keep circulation going.

I can't help with the fuse question but as someone who had a horrible time with my RV ac until I found another option, I just want to share this in case the unit in your RV is toast. If you have a decent-sized window and a few hours this could easily allow you to run a window ac on a small inverter.

I have 6 100 watt panels in 3s2p going into a 40a Epever SCC, a 1200 watt Giandel pure sine wave 12v inverter, and a 206ah Sok battery. I have a 150a Bussman breaker from a smaller planned system that I never used, I know that 150a is the right size for between the battery and inverter and I...

Do I need a breaker between the SCC and battery and if so what amp? I thought the rule of thumb was 10a more than what the SCC was rated for.

I have 2 100 watt hqst panels that I will wire in series and a 30a Epever cc with a 100ah ampere time lifepo4 battery. I only want to supply power to my RV, I won't be using an inverter with this setup. Should I get a solar disconnect breaker for this? Do I need a 40a breaker between the cc and...

I'm hoping to connect them with the 4 I have already in series-parallel, in 2 strings of 3. I have the 40 amp 150v Epever charge controller, would I need inline fuses for 2 strings of 300 watts in series-parallel?

I saw those as well but they changed the voltage and amperage of them but kept the model number the same. So annoying that they didn't just change the model number.

Those were some I was considering but I was worried about the short circuit current (Isc) being 6.5 A instead of 5.83 A . I just don't understand what is most important for matching different panels.

I have looked everywhere I can think of and I can't find a simple and clear explanation for understanding the information about a solar panel. I have 4 100-watt HQST 100D-SSP panels, I need two more panels but I can't find this model # anywhere. I'm trying to find the closest match that I can...

I'm charging right now, and like you said no more sparks. Thanks for the help, I truly appreciate it.

I just purchased the Pro 12v 20A lifepo4 battery charger to charge my Sok 206ah battery and the instructions are very lacking, The little pamphlet said to plug the charger into ac power first which goes against everything I've been told so I didn't plug it in before connecting the clips. I...
