Can home assistant get the read out of battery health from BSL bull batteries? I’m really curious to see how our batteries are with regards to how many cycles has been done etc.

Hi guys, sorry for the delay in the responses. Things have been a bit crazy. Thank you all for the valuable input. @Sc00bs thanks for the video, very informative. i am currently not at home but will definitely look at these suggestions next week and will revert back. Have a great Easter guys for those that celebrate, but most important have a safe one and enjoy the time with loved ones.

Good morning, surely though if it’s not double the size it should split the load still? As an example on average we draw just over 2kw when we don’t use kettles or geysers from the inverter, the generator is enough to run the house, which when the generator is running we don’t use anyway. I mean I understand that ideally you want as much power available to charge the batteries as quickly as possibly but surely with load first set the generator would power the house and take what it can to the inverters?

Good evening all, I have 2 x Deye 8KW inverters connected to 7 x 100Ah BSL Bull batteries and we cannot seem to get the batteries to charge with the generator. The generator is wired to a manual changeover switch so it would be seen as grid if I understand correctly. Basically what happens is that we can turn on the generator and flip the change over switch to Generator and after a few seconds the generator icon appears on the inverter, generator sounds like it’s labouring and then the inverter drops the connection and no longer shows the generator icon, a few seconds later the cycle repeats. It never seems to keep a stable link. The generator is a 7.5KVA Briggs and Stratton generator that is admittedly about 14 years old, maybe older. Our installer doesn’t seem to know why it’s doing that and has mentioned something about a frequency stabilizer as he thinks it’s the frequency of the generator not being stable. Battery Setting has the following settings: Grid Charge and Grid Signal selected Gen Charge and Gen Signal are not, but this could be because the generator is not connected to the Gen Port Gen Force is also not ticked. Gen is not ticked on Work Mode for 9AM to 5PM, so as I understand it generator won’t charge during that time. I’m pretty sure we did set gen charge and it didn’t work either. But happy to try it again if everything else checks out Hope that explains everything.

Ok great that makes sense. Thank you. Will try that out and see how it goes. should get 2.5 hours at a small kW draw am I correct? Usually we will only draw about 2kW in an evening load shedding cycle. During the day Will usually be more, but the solar will be running at least.

What other impact will max discharge have if it’s set to 200A? We are looking at getting another battery, as I do feel that we should have 3 minimum.

The four geysers are all connected on the inverter side and not eskom directly. We have put in 2000kw elements into the geysers. I did test it with one at a time and seems to be working. But this is still with solar, will try with timers again and see what happens when power goes off at night.

Hi Kilowatt Power, sorry for the delay. Never seemed to get. Notification about your response and been a busy few months. Batteries are connected with a cable from the RS485 port, the CAN port on battery 2 is occupied with a cable going to the inverter 1. Inverters are configured to work together. problem has not happened for a while since tweaking some parameters. Just have issues when power trips and geysers are on. not sure if there is a way to run all four geysers, we have put them on timers but it doesn’t really help because load shedding is so dam unpredictable. geysers are running 2000w elements. But it causes inverters to panic and shut down. Not to surprised there. Is there a way to make the work? Do we need another battery or two? Or another inverter even?

Hi all, I am new to Solar and we have recently had 2 x Deye 8KW inverters installed with 2 x BSL Lithium Phosphate Batteries (B-LFP51.2V 100Ah), in the morning with load shedding the inverters shutdown for a few minutes sometimes showing an error and sometimes not. The errors when shown are as follows: F56 DC_VoltLow_Fault on the master and F41 Parallel_System_Stop on the second unit. There is a geyser that switches on at 5AM and off at 6AM, so I think that might been the cause, but I am not sure as the timing is for by a few minutes. From what I've read the F56 relates to the battery configuration. The one battery is connected via the fuse to positive and negative terminals, then the second battery is connected to the first battery. The battery settings on the inverter are as follows: Batt Mode: Lithium Batt Capacity: 200Ah Max A Charge: 50A Max A Discharge: 90A Activate Battery: Ticked Start: 30% (10%) A: 40A (50A) Grid Charge: Ticked Grid Signal: Ticked Lithium Mode: 00 Shutdown: 20% Low Bat: 35% Restart: 50% Battery 1 dip switch is 1 up, the rest down, Battery 2 dip switch is 1 switch down, 2nd switch up and the rest down. Then on the Work Mode, not sure if its configured correctly either. Currently configured as follows: Grid Charge ticked for 1AM to 9AM Grid Charge unticked for 9AM to 5PM Grid Charge ticked for 5PM to 1AM Power is all set to 8000 and Battery is all set to 95%
