Anyone have any solar power generators/power stations they're looking to get rid of. I'm specifically looking for a unit ≥2kWh that has a high wattage solar PV input. EcoFlow Delta 2 Max or Bluetti AC200Max or equivalents. I'm located in central NH, but often travel to southern NH. So I'd...

Looking for a Chargeverter or a somewhat similar 120VAC to 48VDC charger. It will be run exclusively off of a Generac or a Honda generator (not simultaneously obviously), both of which are purse sine wave, though it will still need to handle dirty power. I'm located in central NH, but the...

Anyone in the southern New Hampshire or Vermont area have any large solar panels for sale or interested in splitting the cost of a partial order of solar panels? I really only will likely "need" a maximum of 6 panels for our cabin and can't realistically afford to buy a large amount at the...

Anyone in upper New England going to be upgrading to the new V2 Chargeverter and interested in selling off their V1? Or does anyone just happen to have one for sale? Hit me up in a PM or reply in this thread if you do, thanks. ✌️

At our family cabin we have a Bluetti that runs basically everything we need. But this week we added in a 48v rack battery into the setup and a charge controller and will soon be adding more solar panels. Current setup- Bluetti AC200Max (wired up to AC plugs throughout the cabin as well as DC...

How would one go about wiring up a smart shunt to a battery system that has separate inputs and outputs? I'm using battery packs with separate port BMS (opposed to common port) output leads and input leads. As of right now I have my shunt connected to the output of my system and it will tell...

I came across a good deal on eBay today on some batteries and wanted to share. And I figured this could also be used as a perpetual thread where we talk about goo deals we've found, recommended brands and vice versa which to stay away from.

Could anyone recommend me a good high quality 36v charger? I am running NMC cells and the charger should either be able to be set to NMC, adjustable to 42V or be factory set at 42V maximum. I was previously using a 36V golf cart charger that didn't stop at 42V and nearly charged my system to...

I'm usually not a fan of vague questions like this, but... What would cause my charger to not work? 🤣 This power supply- https://www.amazon.com/dp/B091CL4GB9 I'm connecting is up to a 36v battery setup that consists of 10 individual battery packs all wired together in series. The previous...

This came up for sale near me- https://www.facebook.com/marketplace/item/713764747478048/?mibextid=dXMIcH Thoughts? How easy would a Lithium swap be? 😂🤣 Someone talk me out of what would be a really bad financial decision.

For clarification in this instance "low amperage" means under 10Amps. Please answer the poll above ☝️☝️☝️

So, lots of people have off grid cabins and presumably some of you have all DC lighting. What are you using for switches? Until recently and I knew better I had just been using normal interior 120Vac wall switches. But it had only ever been switching 12Vdc at presumably low amperage and...
