A 250W solar panel only needs to supply 1200W to charge a 1200Wh battery with a 50% discharge rate. This means you need a battery with a capacity of 1200W.
A 250w ebike motor needs at least a battery that can provide minimum power of 250 watts in an hour. Generally, most brand-new 250w ebikes come with a 36v 10Ah battery pack i.e., 360 WH. However, ebike battery size depends on your riding distance, the surface you ride on, your weight, etc.
A 250W solar panel does not need batteries if it is on a grid tie system, as excess energy is collected in the power grid. However, if you are off grid and have to reserve excess solar power, you would need a 100ah battery.
No of Required Batteries (Parallel): 999 Ah / 100Ah = 10 No of batteries. You will have to connect 10 batteries each of 100Ah in parallel to run a 900Wh load (minimum for 3 hours) per day with 2 autonomy days. If you need to install 120 Ah, 150Ah, 200Ah or 250Ah batteries, simply divide the battery bank size by the desired Ah rating of the battery.
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.
Battery Capacity in Ah = (900Wh x 2 Days x 3 Hours) / (50% x 12 Volts) Required Size of Battery Capacity Bank = 999 Ah (Almost 1000Ah) This is the minimum battery bank capacity size you need to run a 900Wh load daily for 3 hours.
