Thanks. I am haveing random failure error 2012 : CAN_comm_FAIL", don't think it is my cable otherwise it would be permanent error. Have you set battery model to "KODAK"?

Hi, by "straight cable", do you mean standard network / ethernet cable? I am haveing random CAN comms failure and battling to solve

Genset on 2 x 60kva Growatt grid tied inverters? Can I connect 2 x 60kva to the load side of contactors on a 110kva generator. This effectively would mean the Grid tied inverters would be in parallel with the generator when manis fails. Concerned mainly regarding any possible feedback into the generator even if feedback disabled. I do not know the Growatt inverters very well and concerned about totally limiting grid export

Would anyone here be able to assist with my repair attempt? I had 2 US2000 fail with obvious swollen cells, I swoped out one cell pack to try make a healthy battery, however the battery now only charges to 80%, however the total US2000 voltage shows as full (53.2V) Battery view shows that the swoped cell pack only gets to around 3.3V per cell while one of the other pack shows over voltage 3.6V, thus the total voltage gets to the 53 plus voltage. I have tried an external regulated power supply to recharge, but once at the 53.2 volts BMS stops the charging with the unbalanced cells. Any idea how I can balance these?

Thank you, appreciate the input

Hi, just came across this after a customer asked me to check his Axpert / Shoto settings. The manual / brochure and suggests 56.4V charge, see from manual and brochure. @Coulomb would you still suggest the Pylontech 5.2V?

Battery view confirms that there was overcharge current on this battery. Also was overvoltage up to 54V on some of the other batteries. Surely this means BMS faulty as the batteries not charging equally? I am suspecting it may even be reporting incorrect values? My charge voltage was set to 53.2V, I have reduced it to 52.4V as advised and in case batteryview was correct, however reading with a Megger brand multimeter, I get a reading of at least 0.5V lower than the reading reported in ICC (which I assume is from the BMS?), so I am suspicious of the records from Batteryview Any assistance would be appreciated, don't want the expense of another battery failure

Bulk 53.2V float 53V

OK, definitely faulty cell. Removed battery from the stack, and properly swollen.

With batteryview I get one cell 3.009V when flat. After charging and no error showing all voltages show balanced and correct Does this indicate a faulty cell?

Having issues with one battery, No. 5 in pictures ICC. For some reason this battery appears to go flat from around 40% as seen in the dip in the attached graph, the graph is showing the entire stack of batteries. They all charge up to 100% again, and all, including No.5 discharge evenly until the 40%odd then it goes down to 2%. I have 7 x US2000 connected to 2 Axpert. This No. 5 battery is around 4 years old and been fine till now

Unfortunately web site takes back to [email protected] Another issue, not sure if related, but the batteries jump from 90% state of charge up to 99% every time, then seems to loose that same 10% fairly quickly. Its like I have 10% less battery capacity. See graph below. At 12h25 full then a jump to99%. Used some fairly large loads down to 85%, then 15h00 another jump to 99%

My original email was addressed to [email protected], the reply I received was from Riaan Heath at [email protected] and copied in was [email protected]. All subsequent replies were the same, never had any reply from Manie, but [email protected] was copied in all emails

Can anyone tell me why I have these spikes in the solar wattage too? This is on a cloudless day, so unlikely to be from cooling, and it seems to happen every day, with or without clouds

FYI, those thinking of buying ICC: I just posed the same questions above to ICC and received a very rude reply from a Riaan Heath of ICC, Diversified Solutions. He basically blamed me for not understanding the ICC, instead of tying to educate me on it. His final words in the email quote "I WILL NOT RESPOND AGAIN, as there is NO USE." Hows that for customer service! NOT I received 10 times better assistance from this forum, thanks guys. Afraid he has lost a customer and any future recommendations for his product
