Hi all,
Thank you for all your help so far in this wonderful forum. Here is the latest diagram that we have with wire lengths and ratings as well as fuse/breaker ratings included:

Hi all,
I was wondering if anyone has/knows a source for high-quality thick gauge stranded copper wires (2 AWG - 4/0 AWG) in/around Vancouver, BC, Canada, or anywhere in Canada with fast shipping.
Something like a TEMCo brand with +105°C rating. Looks like TEMCo wires are not available on...
Hi all,
We are planning to set up a 400W solar setup with 12v battery bank. In our system do you recommend using fuses or dc breakers between
Solar panels array and MPPT charge controller
MPPT charge controller and battery bank
MPPT charge controller and load
Battery bank to fuse box
other...
If a higher gauge wire fits in the terminals, is it ok to always go with the highest gauge possible? Let's say the expense is not the concern.
For example, let's say I need only an 8 AWG between the charge controller and battery bank, and I decide to use a 4/0 AWG wire. Is that bad?
Does...
Hi all,
We are planning on buying 4 x 100 W 12 V Mono solar panels by renogy and put them into a 2S2P configuration. Where should we mount them on our motorhome's roof?
Here is a sketch of the roof with possible panel locations (panels are in white). The 3 big boxes on the roof are rough...
Hi all,
We have created our initial draft of our electrical wiring for our class C motorhome ( 1986 Ford E-350 V8 460 CI with a 1985 Vanguard Coach ). Here is how it looks like:
We are going to have the solar panels in a 2S2P config and the batteries will be just a 4S for a total of 12V.
We...
Hi all,
What is the best option to combine Overkill Solar BMS wires for either C- or B- into 1 wire so it can be hooked up to Battery negative? I think each wire is 10 AWG.
Can we put a ring terminal on each end and connect to a piece of copper bar and have a wire coming from the battery...
Hi all,
We have made a wooden electrical box that stores our batteries, MPPT charge controller, converter, bus bars, DC fuse box, and our inverter. We were wondering what would be the best option to create access to inverter outputs. Should we cut a rectangle hole at the height the inverter is...
Hi all,
We have a class C 1986 Ford E-350 (Vanguard 1985) motorhome. We were wondering about the best fastener solution for strut channels and/or solar panel brackets to the roof. We are planning to install the panels on the front (the cab roof).
Would we just screw them to the roof (and...
Hi all,
We were wondering if it is accepted to use a common hole roof entry for both the:
LTE antenna cables ( Poynting MIMO-3-17 )
Solar panel cables ( combined cables of 4 x 100 W PV panels)
The hole is probably going to be going through our PV combiner box ( we have purchased a big box for...
