To calculate the Watt-hours (Wh) of a battery, follow these steps: Find the battery''s voltage (V) and amp-hours (Ah) from its specifications. For example, a 12V50 battery has 12 V voltage and 50 amp-hours capacity. Multiply the battery''s voltage by its amp-hours to get the battery''s capacity in Watt-hours: capacity (in Wh) = voltage × amp-hours
in short, a 12v 50Ah Lithium deep cycle battery will last about 20-24 hours running a 12v (4.5 Cu. Ft.) fridge and about 9 hours while running a medium size kitchen fridge (14 Cu. Ft.). After this, your battery will be fully depleted, So if you have a lead-acid type battery then the runtime will be half
total output load in watts; Battery Size . battery capacity is measured in Amp-hours (Ah) so to make the calculations easier first let''s convert the battery capacity into watts or Watt-hours (Wh) To calculate the battery capacity from Ah to Watts use this formula Watts = battery Ah x Battery Voltage. let''s take a 12v 100Ah battery as an example
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh ). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) …
Six 12V LED spots with 6 watts each shall be operated: 6 watts · 6 (quantity) = 36 watts. Add 20% power reserve: 36 watts + (0.2 · 36) = 43.2 watts. → A 45 watts power supply would be a good choice here.
Voltage (V) is the force that drives electrical current through a circuit simple wording --- voltage = pressure. We measure the total energy in watts. And the formula for watts = voltage × amps.. 12V vs 24V battery? a 24v battery can deliver twice the power than a 12v same amp-hour battery. So yes, a 24v battery will last longer than a 12v battery on load.

I am using a 2000 watt inverter with 4000 watt surge capability, adequate wiring and fusing for 400 amp surges at 12 volts, 2KW/Hr of batteries, and 220 watts of solar panels on the supply side. We play 4 - 5 each 1/2 hour sets per day at about 100 to 200 watts of audio and 60 to 70 watts of accessories average.
So the watts out will be no greater than watts in. In practice, the converter isn''t 100% efficient, so you will lose some power as heat in the conversion. A good guess for 27 watts out might be 40 watts in, or 50 watts if the brick gets really hot in use. Or you can avoid guesses by measuring the 120V current to the devices.
