On the inverter I selected "user " because if I select PYL, it goes into alarm. I also connected the RJ45 cable from battery to inverter.

I have a Kodak inverter og7.2 connected to 4 Pylontech us3000C X3 & us3000 battery bank. I have observed that 1. when the batteries are fully charged, the inverter momentarily shows 100%, then after 10-15 Min, it drops to 83% and if you load more during the daytime, the display will show a drastic fall in battery level but on the batteries themselves all the 6 LEDs will be on showing they are full. 2. When the battery level drops to 53% or so, the battery percentage drops gradually. So I am wondering is it a battery BMS problem or inverter software problem. How do I resolve it. Thank you

quite interested in coming up with some custom software for my home solar project and intergrate with home assistant if possible. kindly send some more info on the components, software used etc. Thank you in advance

Hello, I have PV system with inverter Kodak Og7.2, 4 x US3000C batteries and 2 strings x 9 Panel ( 345W) .I wanted to find out if I can use my inverter welding machine 160Amps for not more than 2hrs at 30% duty cycle during the peak PV output period. When welding, I will have set it at max 80 amp . Just some DIY works on my gate. See attached graphs. Thank You.

ok thanks @Calvin

Good day, I have a Kodak OG7.2 inverter with 2 strings of 9x 335W panels each, connected to a 4 x US3000 battery bank. I would like to find out the effect of having the same address on all 4 batteries. Previously i had given them different addresses, the first being master and others slave, but the batteries would go into alarm. I do not a Battery software to check, but on putting the similar address on all, it went off. thank you. Leonard
