Apologies for the long post... Over the last five days I’ve been comparing the wave 2 and its standard modes (no modifications) against a 5000 btu Toshiba window unit that I had out in my garage. All tests were started at ~4pm and ran for one hour to try and get similar sun loadings across...

Anyone have thoughts on buying a Chins battery from Amazon in order to cannibalize the cells? The 100Ah is on sale for $360, that's basically aliexpress prices for a DIY battery (with a BMS) without the shipping delay hassle or the time cost of building a DIY (admittedly a small time investment...

Maybe a stupid question, but as long as the MPPT of the solar generator can handle input down to 12v it should be as simple as wiring up a 12v LiFePO4 with the appropriate connector and plugging it in to the solar generator, right? The MPPT should handle the power draw from the 12v battery and...

Maybe a silly question, but can someone help me walk through what the potential panel degradation and hotspot concerns might be with an offset stack of bifacial panels on a vehicle roof? I'm planning to do a double stack of panels with drawer slides to extend at least one (possibly both)...

I'm in the process of planning a sliding solar panel setup for the roof of my RV conversion and I'm pretty confused about how to best wire up a system to capture the most energy. The plan is for two ~400-450w panels (probably bifacial but I don't think that matters much for this discussion)...

Well, I screwed up. I was looking for an LFP to start a conversion and stumbled upon this Amazon listing for a 220Ah 24v LiFePO4 https://www.amazon.com/FOIIOE-24V-VESTWOODS-Bluetooth-Replacement/dp/B0BY295N5Y/. Amazon listing claims it's a LiFePo4, can handle 4500+ cycles, has bluetooth for...

Does anyone have a list (or link to a list) of the many solar suppliers across the US? I'm trying to find one local to Northeast Ohio (Cleveland area) to do an in person pickup of a small order of 4-6 panels to save on shipping costs. Most of the companies shilled on Youtube (Santan Solar...

Anyone have a recommendation for the most compact 1000W continuous inverter out there? There's this no-name brand that's significantly smaller than any other inverter I've found... approximately 100 in^3 and 3lbs. It doesn't inspire confidence that almost all of the reviews were in exchange for...

Does anyone have experience using a 110v to 220v transformer in a mobile application to run 220v appliances? I'm thinking of using a toroidal based transformer that's typically used for US to Euro appliance conversion. The specific use case is to run a 220v mini split which typically has better...

This isn't specifically for the solar portion of the system, but this seems the best place to discuss fire safety of electrical enclosures in vehicle mounted systems. I'm starting to plan out how I want to design my electrical enclosure to be as fire safe as possible and it's led me down a ton...

I feel like I'm missing something when deciding how to handle DC-DC charging a house battery while the vehicle is running. I'll have a 24v house battery (NMC) and a 12v lead acid starter battery in a Chevy Express 3500 based vehicle with a 105amp alternator. What seems like the most common...

Has anyone purchased a Fivsta Sola panel from Amazon and have experience with them? Looks like they're a relatively new brand on Amazon and they have some interesting panel sizes (squarish, as well as long/skinny) compared to others, as well as bifacial options. The 200w squarish bifacial is...
