How bad of an idea is it to put a 20am MPPT solar charger in a weatherproof enclosure similar to this without any ventilation? https://www.amazon.com/dp/B09NLW5HMX?psc=1&ref=ppx_yo2ov_dt_b_product_details This would essentially allow me to have the MPPT solar charger exterior of a travel...

Maybe my question wasn't clear. I'm not worried about the crimp connection inside of the MC4 since I can solder the connection. I'm primarily concerned with the strain relief clamping down and creating a watertight connection on the small diameter wire.

I recently purchased a small 30W solar panel to connect to a PWM SCC to serve as a trickle charger for 12v batteries at my hunting lease that sit for long periods of time. The question I have is the 30W solar panel has bare ends and I would like a waterproof connector like MC4 but they're 16...

So the business case for investing more in a 800w array is as follows? A 800w array in 100% sun (perfect conditions) will be limited to 520w by the MPPT. A 800w array in 50% sun will pull in 520w (hypothetical) while a 520w array (sized for the MPPT) will pull in 300w.

Quick question. Looking at the Renogy RVR40 MPPT solar charge controller I see that the specification states the max solar input voltage is 100v and the max solar input power at 12v is 520w. I assume both conditions have to be met and I couldn't put four (4) 200w panels in series with a VOC of...

Good morning. Quick question. I'm looking at purchasing a Rover 40amp MPPT solar charge controller based on Will's recommendation. Based on my research this solar charge controller should be fused with a 50amp breaker and 6awg is acceptable for 50amps but the solar charge controller will only...

Signature Solar is out of Sulphur Springs.

I will be in receipt of a Overkill Solar 4s BMS 120a LifePo4 soon and I’d like to go ahead and order the lugs. Anyone know which lug fits 3 10 gauge wires? Thanks in advance.

Agreed but my question is more general. Even when switched is it safe for a MPPT SCC to have a DC power supply @ 48v 10a for AC charging?

I was watching Will's 1st milk crate video and noticed that he connected a DC power supply (AC 110v-20v to DC 0-48v) to the MPPT solar input to boost the charging amps. Is this safe to do?

If you don't mind me asking, where did you purchase that crate? Convenient to have the flat area to install the DC outlets and battery monitor.

Good morning. I'm planning out a schematic for a portable solar build and I have a question related to the AiLi Battery Monitor. I intend to install the battery monitor in a milk crate similar to to some of the recent YouTube videos. Since it will be permanently connected to the battery I wanted...

If I understand the question correctly you're explaining what shown at this link under the "How To Configure Cells In A Large Battery Bank" section. https://www.mobile-solarpower.com/design-your-own-12v-lifepo4-system.html

I'm piecing together a 2200W solar system for an off grid hunting cabin. Currently looking at a 2200W 12V pure sign wave inverter and I'm attempting to size the wire and fuse. Here is my logic: 2200 inverter watts / .85 inverter efficiency = 2588.24 DC watts / 12V DC = 215.69 max DC Amps Using...
