I have 4x5000 units. Installer fitted 2 of them when i went ashp and solar. I realised quickly 10kw was not going to be enough so fitted another 2 units myself. Simple as it gets with these units! They have had a thruput of 4.8Mw so far and still showing 99% state of health! Took over a year to drop from 100% SOH so I'm impressed so far.
Hi Ben. Thanks for your video. I am having a problem with since i added a new US3000C to my 3 x US2000 stack. I had to put the US3000C at the bottom as it was too heavy for me to put at the top of my shelving - i'm a solo female so dont't slate me!!!! This was a bit of a mind-bender as i had to do all the cabling in reverse adn as easy as it sounds, its not! I had to wire the link cables bottom to top instead of top to bottom as the new master US3000C is at the bottom of the stack. My head hurts!!! Anyway, for the first 7 months everything was fine. Except i noticed one SOC LED on two different batteries was a lot duller than the others. But they seemed to charge just fine. (In one part of your video it looked like your middle battery also had a faint SOC LED?) Anyway, my system shutdown a couple of weeks ago when there was no sun for a couple of days (which has happened max 10 times over 4 years as I am totally off-grid in Spain) . Usually when this happens, it can unbalance the batteries until they reach approx 90% charge, and then they rebalance. This time however, they just wont rebalance. The one with the dull 4th SOC LED will not charge past the 3rd SOC LED. I am assuming this means that the 4th cell(?) is defective. I have contacted Pylontech and they have requested me to access the BMS log and send it to them. Have you ever done this and can you give me any advice?
Hi, I have not tried to connect via the battery BMS. I emailed Pylontech asking them what I need to do and what cables I need, never got a reply from them. Have you tried taking out all the other batteries and charging up the one that seems to be low, then introduce the other batteries back into the string. And yes those batteries are heavy, the US5000 was a back breaker for sure.
I'm about to add 4 x US5000 to my existing bank of 10 x US3000C. Reading the available information (Pylontech and Victron) it is strongly recommended that the new battery/batteries be individually charged to 100% (they ship at 50%) and the existing batteries should also be at 100% before the new batteries are connected in parallel to the rest. Then you should do the 15 minutes or so of idle time so that the batteries do a final equalising phase. Apparently, the batteries will not equalise properly unless this procedure is followed.
I have not come across that before, especially not from Pylontech. I do need to sort out a lead to plug my laptop into the batteries to see what is going on.
Hi there. I read that (and did) make sure that all batteries were at 50% before connecting them and that worked fine until now, 7-8 months later. How did you get on?
Not necessarily, this is what it says in the manual. Consider the following points before selecting where to install: Do not mount the inverter on flammable construction materials. Mount on a solid surface Install this inverter at eye level in order to allow the LCD display to be read at all times. The ambient temperature should be between 0°C and 55°C to ensure optimal operation. The recommended installation position is to be adhered to the wall vertically. Be sure to keep other objects and surfaces as shown in the right diagram to guarantee sufficient heat dissipation and to have enough space for removing wires.
@@Bensgarage if you keep the Growatt on sometimes blow with the air compressor inside and clean the dust because if the dust is settles the inverter is not gonna cool down and he’s going to create again the problem what you have 👍🏻
Easy enough to install in our battery stack, and it's working well.

Be interesting to see it when we get over there!
It doesn’t really matter which is your master, all you need to make sure that (as you say) the older ones (eg US2000) is that the end.
It probably doesn’t matter, but in the us5000 manual it shows putting the 3000s and 2000s underneath it.

Did the additional battery increase the charg discharge rate of the older battery??

@@moxiejohnson4090 No issues at all, but it has only been a few weeks.
Hey Ben I think inverters are meant to be on an outside wall but under cover
Not necessarily, this is what it says in the manual.

What happened with powmr
I want to buy one but i still wetting for more research but I want to buy 10.2 kW do you think is better ?
I have no idea about other models of PowMr, just that ours only lasted eight months. They are sending me a new board to hopefully try to fix it.

did u set menu 5 and 36 ?
Yes, did that when we first set it up a couple of years ago, it remembered the settings after fitting the new motherboard.
how long did growatt nowatt last ?
It's still working from when I fixed it, no idea how long it will last.
