Example 1: To charge a 20Ah, 36V battery within 6 hours: 250W solar panel (4 panels) Example 2: To charge a 50Ah, 36V battery within 3 hours: 600W solar panel (4 panels) Example 3: To charge a 100Ah, 36V battery within 12 hours: 400W solar panel (4 panels). Example 1: To charge a 20Ah, 36V battery within 6 hours: 250W solar panel (4 panels) Example 2: To charge a 50Ah, 36V battery within 3 hours: 600W solar panel (4 panels) Example 3: To charge a 100Ah, 36V battery within 12 hours: 400W solar panel (4 panels). To determine your battery's energy requirement, multiply the battery voltage (36V) by its capacity (Ah) to get the total energy requirement in watt-hours (Wh). For example, a 36V battery with a 20Ah capacity would have an energy requirement of 720Wh (36V x 20Ah). What Affects The Solar Panel Size. . Enter the total solar system size in watts: If you have multiple solar panels connected together, add their rated wattage and enter the total value in watts into the calculator. What size and how many batteries do i need. I'm assuming a mppt charger but what kind as I see there are a few dif kinds. Any ideas or a wiring diagram would be real helpful. Then you will need to add about 10% due to the inefficiency of the power inverter.
