Hi, am using the 48v KREON, it has low idle power, about 30 watts. But as for the output, its 230v and both poles are LIVE (L) instead of 1 L and 1 N, am not sure if this applies to all LF toroidal inverters, seller says that its both L

I have 3 x 400 watts panel in series and a 3000 watts off-grid toroidal inverter. Not sure if these 2 needs to have its own ground rod. Solar panel has its own DC SPD and Inverter its AC SPD. Ground rod is 5/8". 10 feet, copper Thanks!

Be warned. The Max Head lift is misleading. Max Lift that unit can lift is just 25s meter and not 70 meters as advertised. I got the info from customer service email, that it can lift that high (70m) but only for few min or seconds. Bought 3 and all are dead in 2 weeks time.

Am using Deye Hybrid Inverter, and its set to Lithium Mode, which communicates with the BMS of the powerwall via LAN cable. Seems to be doing the job. And yes, i kept the charge to 85% which is equivalent to 52.3v (4.02v/cell). When it reaches that voltage, The Deye ineverter goes to idle...

Thanks for sharing your setup. My 2 solar wall communicate via LAN cable then another to LAN to the hybrid. Am keeping max charge to 52v (says floating voltage) and thats about 80% total capacity with each cell about 4.01. Unfornutately there is a difference of 5ah between the 2 powerwall but...

It has 13 cells

Have decreased charging to just 85%, previous pic showing 90% of the cell voltage were almost 4.1v. Manual says it has equalization voltage of 42v, its has HVD and LVD by itself, which is good. Just really confused with this kind of battery As always, appreciate your input snoobler

Upgraded my system. 1st day of operation. But 1st time using this NMC batteries. Is it best to charge it 100% or just 95% like LiFePo4?

I have One Solar 48v 100ah NMC Battery (BYD). its connected in parralel with recommended charge at 0.2c. Found out its 13s My concern is, would be better to charge it up to 100% or just 90-95% like LiFePo4? And are nmc really that combustible? This is connected to my Deye 5KW hybrid inverter...

I fully understand the BMS limitation. So regarding the maximum # of 3.2v cell to parrallel, is there is really no limit or recommended number of stacks? Was planning to build a 24v 400ah system, using 4p8s of Sinopoly 3.2v batteries connected to 3kw 24v Snadi inverter. I wont be using the...

Am using the 5a Heltec, old version i think. Before my these cells gets unbalance with 1 reaching 3.73, 4 months now with balancer and seems to be doing good. i also have the newer 4s version of heltec, the max i got was 2amps transfer, but since my bms also has passive balancer, not sure it...

thats also my thinking on this. thanks

34 usd each, 6 months ago, now its just 20usd. i think its from used electric buses

I bought some second hand Sinopoly 3.2 100ah batteries (but sold as 90ah, marketing strategy). I found out is 100ah based on the model. Anyways tested the capacity and its >90ah, playing between 91-93ah, at least it is still >80% of 100ah. But is there anyway to estimate remaining cycle for...

Appreciate your feedback, am using a Solis Grid tie, i think this is a good one, been using it for 9 months now. It has a limiter and sensitive enough to shutdown for any voltage fluctuation in our area. And yeah my main concern is i dont know which of the 2, the GT or Mppt will max out the...
