Thanks for your help. Great job. I bought the BougeRv Solar charge controller to replace the one I got with my Eco Worthy solar panel and with your install and how to work the controller I couldn’t be more happy. I want to put two 100 watt panels on the south facing side and two 100 watt facing the west side of my roof. Will the BougeRv controller be ok. Keep up the good work. Looking forward to future videos.

That is about the same set up I have. Two on the east side on my deck roof and two on the west side on my small shed. However, I have two Bourgerv 20 amp PWMs for the two sides which are connected in parallel on the 100 watt solar panels and I also fused them with mini 20 amp fuses to the battery. If I had three panels at each end then I would have used two 30 amp Bourgerv PWMs. I do like the simplicity of how to use the function keys to set it up for my 150 ah Eco Worthy metal case battery to run my 2000 watt inverter (added note...set the charge controller to 14.2 rather than 14.6 to ensure the battery's life span). I have limited space inside the house and the two PWMs sit perfectly on the small board with the 200 amp fuse and two bus bars. If you do a search on Google, Duck Duck Go or whatever, you can find PWM or MPPT calculators which helps in selecting the device for the solar panels to charge the battery. The PWM is the easy one since it only asks for the short circuit of the solar panel and how many panels you have. After the information is given it calculates the amperage for the correct PWM. For an MPPT it ask for the wattage of the panel, the open circuit, the short circuit, how many panels are wired in series and in parallel and what is the coldest day of the year. This information given calculates what MPPT to have. Since we both have two locations for solar panels it would be wise to have two MPPT controllers since the two locations are wired in series. To join them both would result in having a parallel connection and that would go over the maximum voltage of the MPPT unless you buy an expensive Victron that is designed to handle above 100 volts.

Hello new to your channel good information for start up beginner solar. Would it be possible to show or make video on your solar panels, install, series vs Parallel, solar controller amps, how many solar panels can handle etc...... thank you for videos.

These kinda things are what I'm looking for, the entry-level, lower-priced stuff. One concern I do have about the heatsink, it's on the back, where it'll be pressed right up against whatever surface that it's mounted to. I'd rather see the heatsink more exposed, so it could dissipate the heat better, but I see WHY they made it like they did (display up front, no room for heatsinks there). If heat becomes a concern, one of those little USB powered fans (AC Infinity makes some nice ones) under the unit, blowing upwards would absolutely fix the problem.. Could even be plugged into the supplied USB port, so it'd be active only when you've got incoming solar power (I'm assuming that's how that port works anyway, but it may also pull power from the battery bank when there's no solar input). I REALLY need to put a temporary camera up on my out building pointing towards the south facing roof on our house to see how much solar exposure we get on any given day without any tree modifications. I have a feeling though that I'm going to have to take down some trees to get any meaningful power generation :(.

You mount solar components on a fireproof material for safety.

@@williamkn621just because the surface is fireproof, doesn't necessarily mean it'll be able to pull the heat away (IE: type c or x drywall are generally thought of as fireproof, but they're really just more fire-resistant). Guess the only way to be 100% sure it's fire proof is mount them to a metal plate, that'd also double as an additional heatsink.. Most solar installs I've seen mounted the stuff to the drywall in a garage, or on a mounted piece of plywood (but I've only seen a couple installs in person, so who knows if that's up to some sort of code or not).

What experience I have with mppt charge controllers with rear heatsinks is they were pretty oversize and didn't get very hot as they were at capacity (amps). No experience with pwm controllers. At least yet. The price of this pwm controller is kinda close to 30a mppts from good middle lower brands. I'm halfway considering figuring out the OEM for this since this is pretty obviously a branded part

I gotta cut down a big trashy Chinaberry tree already damaged by our big freeze in Texas a few years ago. It blocks late afternoon and evening Sun on one of my ground mount arrays (a pergola type shade). And panels on my workshop. I established some shorter shade trees under it so we still will have some shade but no where near as tall The USB ports on pwm and other charge controllers are generally able to be programmatic set. So yes, run a muffin fan when solar is producing

No. They have to be wired in parallel since series would burn up the PWM.

PWM? Okay to start, but you need to keep the solar panel voltage near the battery bank voltage because it cannot convert down but will simply discard (in practice) the excess. Don't pay much for a PWM controller as it is a disposable item if you keep moving on the solar journey.

@@maybee7126 They most likely use it to charge a lead acid based battery. Here is a neat trick to pass on to your friends. Ali Express has buck boost step up converters (they changed the name to charger to get more money for them) which can take the charge voltage from the PWM and convert that voltage to 14.5 volts to charge a Lifepo4 battery(s). It can be directly be hooked up to a 100 watt solar panel (my open circuit voltage is 24.5) since the converter can handle up to 30 volts to convert to 14.5 volts. They cost $21.50.

Sam i don't want to knock u but i would be careful with those cheap Chinese controllers.. They may cost more than u think if something fails and they over charge ur batteries and now ur batteries are trashed ... Im just saying we been off grid for 7 year's never trust a controller under 100.00 unless u only have one battery for like lights or security cameras just trying to help u out brother....
