How much power does a 12V inverter use?
For example: If you're running a 1500W inverter on your 12v battery with 1000 watts of total AC load. So your inverter will be consuming 83 amps (amps = watts/battery volts) from the battery for which you'll need a very thick cable. using a thin cable in this scenario can damage the inverter or you'll not be able to run your load.
How much power does a 48V battery use per day?
To calculate the battery size, start with the power usage from the batteries in one day: 5000 watts / 48 Volts = 104.17 Amps. For a 50% Depth of Discharge (DOD), the minimum battery bank size would be 208.34 Amps * 48 Volts = 9798.52 Wh or 9.8 kWh. The charging rate is 1243 Watts @ 59.2 Volts, which derates to 1615 Watts. So, you would need a solar array of approximately 1615 Watts.
How much battery do I need to run a 3000-watt inverter?
You would need around 24v 150Ah Lithium or 24v 300Ah Lead-acid Battery to run a 3000-watt inverter for 1 hour at its full capacity Here's a battery size chart for any size inverter with 1 hour of load runtime Note! The input voltage of the inverter should match the battery voltage.
What is the surge requirement for a 6kW inverter?
For a 6kW inverter, the surge requirement is 12,000 Watt * 1/48 volt battery bank * 1/0.4 maximum surge current = 625 AH @ 48 volt battery bank. Keep in mind that your battery bank requirement for 2 days of battery use and 50% maximum discharge is 10 times the surge requirement.
