Re: Nyx frame, 273mm*40m V3 hub, and 650A

I noticed doctorbass has been largely absent as well, though that could just be a coincidence. I've read through many of the old posts here at ES and it seems that at least a few of the people who seemed to be on the bleeding edge circa 2015 or so are either notably absent or no longer contributing...

I am actively searching for a inverter that is: -1 or 2 MPPT input ( idealy starting from 60VDC and not 200vdc as i have some string of 2x 60 cells panel only) -Grid Tie -Hybrid (battery backup input) -48Vdc ( not 24, not 12) -Certified UL or CSA. - 4kW and more It seem a real pain to find some that...

Thanks cricketo, I did not know that there are battery-powered off-grid inverters that generate the sine wave necessary for grid-tied inverters. And that SMA does that. I saw great bargain of some large SMA inverter at very nice price however these are not split phase so you need two that i guess ar...

Hello guys, In my solar project i am making some testing prior to see if some concept are working. You can get very cheap used old micro inverter like the Enphase M190 and to increase their power you can paralle them if you use these outside their MTTP voltage range when powered by battery.

Re: Inverter recommendations, 48V sine wave, no grid tie

The cheapest way to convert 48Vdc to kW of sine AC is to get used UPS !!! I got a APC 5000VA ( 4300Watts) for 200$ no battery inside. It work really well for the cost!!! similar to this one.. but it output 208Vthat i converted to splitphase 120-120AC https://www.kijiji.ca/v-electricite/laval-rive-no...

Motor torque generally doesn't mix well with suspension forks.
