if i had 500 watt solar system with a 40A MPPT charge controller, would it be better to have 1 or 2 SOK 12v 100 ah batteries or have 1 SOK 12v 206ah battery ?
this is very helpful, could you explain why this is the case?in fact, it depends on your inverter, if the inverter under 2000w, i suggest just one 206Ah, if 2000W~3000w, i would suggest you get 2 100Ah.
Both the 12V 100Ah and the 12V 206Ah SOK batteries have a max continuous discharge capacity of 100A, and a peak of 200A for 3 seconds. Two of the batteries in parallel double that to 200A continuous and 400A peak.this is very helpful, could you explain why this is the case?
For a 24V inverter you need two batteries in series to get 24V. A 2.4kW inverter at 24V is 101A. So it's fine to have either 2 100Ah or 2 206Ah SOK batteries in series since the two in series gives 24V and you get 100A continuous discharge with the batteries. You could put 4 100Ah or 4 206Ah in 2S2P if you needed 24V and you wanted more storage. You also happen to get twice the discharge amps due to the 2P aspect but it's not needed in this case. It just gives you twice the storage of just 2 batteries.So if we put this into practice, on a 24v 2.4kw (like the 2424) system a good , but close to max, solution would be two 12v Sok 100AH in series, which would keep the batteries at 100A continuous (series v parallel).
Don't think about series or parallel being better for battery health. You put batteries in series when you need higher volts. You put batteries in parallel when you need more amps. You can combine both when you need both more volts and more amps.Series being better for battery health long term v parallel?
You need 24V for the 24V inverter so you can't use just one 12V battery regardless of its capacity. You either need a 24V battery or you put 2 12V batteries in series. You can choose 2 100Ah or 2 206Ah based on how much capacity you need.But a better solution would be 1 206Ah 12v Sok, best being 2 206ah 12v Sok?
min is off a bitin fact, it depends on your inverter, if the inverter under 2000w, i suggest just one 206Ah, if 2000W~3000w, i would suggest you get 2 100Ah.
For LiFePO₄, 13.0V is more like 40% SOC, not 95%.it says about Battery volts 13.00 and Capacity is about 95%
