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...

Oh defenitely will not happen. Out average temp here is 86 F, coldest ever recorded was 75 F :)

Hi, can anyone comment on my planned project. So i have a total 1,200 watts panel which supplies my current 1Kw Grid tie system. I want to add another MPPT in parallel with my Grid Tie, both getting power from the Solar Panel. Will this work? My thoughts: both grid tie and mppt will get...

50a DC

Sorry for the confusion, the pic i showed on my reply was the voltage with the active 5a balancer and not with the Bg-8s which really is just a passive one and really just good as a monitor. Here is my active balancer that got fried. Thanks for the advice, have adjusted my abs voltage to just...

Yeah this happened now since my active balancer got fried. waiting for replacement. but with the balancer all cells are at 3.55 The mppt is at float mode with that pic. This pic is with the 5a Active balancer. Absorption charge set at 14.1v and float at 13.5 x2

Shifted to LiFePo4, I dont like the Lead acid batteries The system is for temperate region, wet and dry season only. The 24v system consist of: 8 x 3.2v Sinopoly Battery 90ah LifePo4 (2nd hand) Bms generic of Daly, 60/30 Victron smartsolar 100/20 24v to 12v 10a converter 1 x 340watts JA...

Just trying to copy how everyone do their grounding. We dont have any lightning strikes in our city.

Thanks for the input! Am located in the Philippines and we really dont have any clear regulation on the grounding requirements. Was able to buy the 3.5sqmm, the 4sqmm is not available locally, the next size is 5.5sqmm. Wont be using any inverter in my system, just purely the 24v converted to...

Hi, 1. Wanted to ask for help for an off grid system im building. Am hooking a 340 watt Poly panel to my 24v system. Want to get your advise on what is the the accepted ground wire size ( Panel is about 4 meters away from the ground). 2. And another thing i would like to ask, if the panel...

I set the absorb to 14.0 and float to 13.5. Your right i wont be using the entire capacity, just less than half. Just made it bigger for possible bot so sunny days. Thanks!

Oh yes, it will be mounted vertically, i havent installed it yet My main concern is the temperature, since the cabinet is exposed outside, max i got was 41 deg celcius. Am I right to assume, keeping battery below the 45 deg Celcius is acceptable? No way i will get a 25 deg in my area without a...

Good day, A lot of thanks to Mr Prowse and i ventured to the LiFePo4 from lead acid batts. Here is the background of my Setup: 24v system - 8 pc 3.2 Sinopoly LiFePO4 (second hand) 90amps. got it for (est 300 USD total) with a 8s BMS (Daly generic i think) - did bottom balance then top...

Seems to be working well. Prior to using this, i get into abs/Float Voltage phase with cell 2 and 7 having 3.7v and yhr rest are 3.4, now everything are almost the same voltage. Happy with it and i bought similar unit but 4s. same results. Second pic is the model for 4s, no need to solder, amd...

Initially i thought battGo battery monitor with balancer was ok, but found its really slow and just a passive balancer. saw youtube videos by j.legazpi which convinced me to buy this active balancer. says 5a. Just installed it today and will see the result. Hopefully Mr @Will Prowse can do a...

power surge i guess

This is very informative. I plan to Setup my Victron 100/20 with LiFePo4 w/ BMS for my aquaponic system. My concern really was what if the BMS cut off the power while my pump is connected to the Load Output of the SCC with the Full Sun, you gave me an answer. I will still add an additional...

doesnt the controller have its own fuse to prevent it from damaging if the load output short circuited. Am also using a 24v to 12v stepdown on my loadput to power my water pump, luckily its still functioning.

Hi, thanks for the advice Am new with LiFePo4 batteries, hence wanna start slow. instead of using the 32650 batteries, i just bought 4 pcs of 3.2v 90ah Sinopoly LiFePo4 battery with Deligreen 4s BMS 30ah discharge/15 amp charge and hook it to victron 100/20 mppt smat solar (will cap max charge...

Hi, just wanna do some DIY project. Am planning to use LiFePo4 3.2v 5ah 32650 batteries. Design would be combining 5 batteries in parallel to make a 25 ah bank, then 4 series to complete a 12v 25 ah battery bank with a 4s BMS. My concern is, can i make another same 25 ah battery bank with...
