I'm going to buy a 50Ah battery (probably LiTime) to put on my motorcycle. I found this 8A DC to DC charger, which I can run off my bike. https://powerwerx.com/dcdc-charger-lifepo4-8a-adjustable Do I need to buy anything else? I just need to run 12v devices.

I watched Will's video on signature solar rack batteries and saw they had chargers. They claim to be 95% efficient. While I haven't looked in a while. I don't know of any chargers that are that efficient. Does anyone have their 24V / 40A charger and can confirm it's really that efficient?

I heard that your solar panel voltage should be at least 20v over your battery bank voltage. I assume that this is because the higher the panel voltage the less sun it will take to get power in and get above the battery bank voltage so your charge controller starts charging. So they start...

I found a good deal on 200w panels. $606 for 4. Specs Maximum Power Voltage(Vmp): 20.4V Maximum Power Current(Imp): 9.80A Open Circuit Voltage(Voc): 24.3V Short Circuit Current(Isc): 10.2A I'll be using (8) 280ah cells configured as a 24V battery. I've heard you want your PV voltage to be at...

What is the consensus on the quality of Rich Solar 200 watt panels? Is there a better brand you would recommend? I have limited space and I need to get the most out of it. I can mount (4) 200w panels on the roof of my SUV with a slight overhang. I can mount an additional 2 panels stacked...

Ordering 280ah cells out of China. Everything else is coming from the US. If I ordered everything today. I would have within 2 weeks except for the cells, which I assume would be 8-10 weeks to receive. Can you set up everything and test that it works without having a battery bank attached...

Does anyone know of any 200w or higher panels that are smaller than 58.7 x 26.8?

I have an SUV, the roofline approx 106" x 52" I need to put at least 800w on the roof. I could put (4) 200w panels and would have about 3.5" overhang on each side and couple front or back. Panels are 58.7 x 26.8 I can put (2) 410w panels (stacked) on it. The bottom one would slide out. No...

I'm going to order some Trina 410w TSM-410-DE15H(II) Solar Panels. I only need 2 and will cost me $283 each with shipping from ecodirect. If I buy 4 or more from Solaris / shipped it's a better deal. https://www.solaris-shop.com/trinasolar-tsm-410-de15h-ii-410w-mono-solar-panel/ 4 - $253...

Has anyone built a dual-level solar panel roof rack? I'm going to put (2) 400w panels on top of an SUV and have the bottom panel slide out. Going to do the same with (2) 200w panels on top of a custom cargo box I'm building. The cargo box will also have a spot to mount 2 additional 200w panels...

I'm looking at the Sterling Power 12v to 24v battery/battery charger Model# BB122470. Is anyone here using one of them? Is there a better choice for a charger? Should the alternator be upgraded to a high output? I'm getting (8) 280 ah cells and will run as 24V battery. Will likely get...

Four 410w panels with 51.2 VOC If all four are wired in parallel the total VOC remains 51.2 - Yes? I ask as Victron 100/50 (24v) controller is 100 VOC max. So the above will work - Yes?

I'm piecing parts together for a system. I'm looking at getting the below 24v / 50a battery charger. Do you just wire it directly to your battery bank? I assume that as long as the existing PV plus the charger combined amps doesn't exceed BMS max. You are fine to run them both at the same...

I'm looking at Go Power GP-ISW-700 ($299) inverter. Specs say it's 93% efficient for 24v version. https://gpelectric.com/products/700-watt-industrial-pure-sine-wave-inverter/ All I have is an AC (410 watts) and a 40" TV that I just ordered and the manual says it 36.7 watts (we will see). I...

I'm looking for a low-wattage 40" TV. Does anyone have one? Many TVs don't list the watts and all smart/4K TVs use too much power. The energy guides seem like they are BS. One I was looking at said it uses 62 kilowatts per year. Which is based on 5 hours use per day. Which would work out to...
