A little bit confused> I have one of those "all in one" 24v inverters (such as this: https://m.media-amazon.com/images/I/61AP9YfHcmL.jpg ) and when the inverter is on. the "AC IN" ports between Ground and live and Ground and neutral show a voltage of around 80-100V. No voltage between Live...

My aliexpress hybrid inverter is working all good, no issues, very happy with it. I was grabbing the AC in plug to plug it in and charge the battery and surprisingly i got a light shock off the plug terminals. Grabbed my multimeter and it's registering 70v~ between positive and ground, or...

hey guys, using a dc power supply (small 30v10A one) to top my lf280Ah and im a bit confused. I've used this power supply on little diy projects before, always worked fine. on its own the voltage is spot on, etc. now the issue i have. I got eve 280ah cells all hooked in parallel. set the dc...

If a solar panel has 41 VoC and 34 Vmp what sort of voltages do you get of it through the day? I ask because I'm building a system that will likely be 160VoC/136Vmp (4 of above in series) on a controller with mppt range of 120-450v Is it safe to say the panels will reliably output over 30v...

if i connect 2 40v panels in series to a hybrid inverter when the "MPPT Range" is 120~450V what happens? Do i need to hit 120v to even work, or is just an optimal zone? This is from a 24v hybrid inverter. Looking to charge a 24v battery with 2x 460w panels which in series won't reach the...

Apparently, they're made out of the factory without threads/terminals, just with a weld spot and claims they weld studs on them? Did anyone order these? https://www.alibaba.com/product-detail/New-Version-Genuine-Grade-A-EVE_1600191410096.html

Might be a long shot as most here are in the US. Struggling on which to buy from as the usual recommended alibaba supplier (Amy Wan) is almost $750 on shipping cost alone to UK even if you just order 1 cell + import duty on top. Would prefer from aliexpress just not sure who is trustable or...

Instructions and all videos I see with them seem to either use a amass or pylontech batteries. My question is, can you use diy bateries with these inverters? If not, is there any hybrid grid tie inverter (legal/export limiting/etc) that allows for diy batteries?

Started making my own solar heating panels for my inflatable hottub Looking forward to test them out in the summer : 2x 4'4' panels with 66 meters 13/16mm irrigation tubing each. Powered by 18W12v pump on a thermostat swithh and a 60w panel hooked to a small " solar generator "

thoughts?anyone ordered these yet?

Logic to me says 16s (51.2v) but there's also bms's for 15s, so not really sure. Planning to make a 48v280ah battery out of 3.2v 280ah cells

Are these cheapo "all in one" charge controllers any good? (more leaning into the 48v setup , also as its also mppt controller, not pwm) https://www.ebay.co.uk/itm/5KVA-Solar-Inverter-48V-230V-Pure-Sine-Wave-Off-Grid-Built-in-80A-MPPT-Charger/353284923580...
