You can use 24V or 12V batteries for a 10kw solar system. To handle the system output, connect them in series to increase the voltage. However, using 24V batteries requires 1666 amps.
The first calculation will be the same as the lead-acid battery. We will still use a 24V battery system. The c-rate of a typical lithium (LiFePO4) battery is 1C. So our 24V battery needs a capacity of 83Ah to work efficiently.
Now that you know you should use a 24V battery to run a 2,000W inverter, we can look at the capacity and the C-rate. The capacity of the battery is indicated in amp hours or simply Ah. The most common battery will be 12V and 100Ah. The battery capacity ties in directly with the C-rate of the battery.
If you want enough power for 3 days, you'd need 30 x 3 = 90 kWh. As discussed in the post above, the power in batteries are rated at a standard temperature, the colder it is the less power they have. So, with batteries expected to be at 40 to supply 10 kWh, with this data you'd multiply by 1.3 to see you would need 13 kWh of batteries.
To achieve 225ah of battery capacity at 24 Volts, you will need to connect cells up in series and parallel. Connecting batteries in Series is when you connect the positive terminal to the negative terminal and so on as shown below.
You need that 6 kWh/d day when the ambient temperature will be 60F: 45,000 X 1.11 = 49,950 Wh. Let use a 48V battery string. Watts = amps x volts, so amps = watts/volts: 49,950 / 48V = 1040 Ah How do I design my Battery Bank? When using lead-acid batteries it's best to minimize the number of parallel strings to 3 or less to maximize life-span.
How Many Batteries Do I Need For a 10kw Solar System?
