I have 4 x 24V 200ah batteries and the bms's do not communicate with the inverter, so must do custom settings on the inverter, below are the recommended settings from the spec sheet. Max Charging voltage 29.2V Floating Charging Voltage 28.8V Cut off Voltage 21.6V Max Charging Current 100A I need to know from the knowledgeable members what would the custom settings be regarding the following: Battery return to grid voltage Switching back to battery voltage Battery Shutdown Voltage Constant Voltage charge Floating charge voltage

Demo, in answer that wont give you 96v in parallel, in series yes, the volts will stay the same in parallel

sorry there was a typo, not 180A but a 160A

Its a conderenergy 5kw 24v with 50mm core cables from batteries to 350a bus bar then 90mm core cable from bus bar to 250a disconnect fuse box then into the inverter

Yes they are connected in parallel, so I should be able to run the inverter at maximum of 180A

I have 4 x 24v 200AH batteries connected to a bus bar, the spec of the batteries are 100A max continuous charge each, will the 100A be diluted by 4 from the inverter or does that not matter as the amperage will stay the same to each battery no matter how many batteries are connected to the bus bar?

Thanks Stefan, all from the same place👍

I am looking for 350a 5 or 6 pole bus bar (x 2) plus a 250a dipole fuse disconnect. Any help would be appreciated

That is how I see it as well, thanks HennieL

the length of the cable to inverter is 970mm, so this must be doubled for both negative and positive

Sorry late with this info The batteries discharge current is 100A The length of the cable to inverter is 970mm, so we can work off 1m each, I have 4 of these batteries in parallel connected to each other by 200mm cables

I cut some insulation off and the strands are coated, I scraped some and the strands are copper

I will cut the insulation and expose the strands and send the pictures for clarification, I used the cable on the left of the first photo

Thank you for the info.

My 24V 200ah batteries came with what I can measure are 5mm core battery cables, I was not happy so used 8mm core battery cables. My question is why do they supply such thin core battery cables, surely it can be a fire hazard, I have attached a photo for size comparison
