If you have enough solar panels and battery banks, you will be able to power a 7.5hp three phase motor. The average solar panel is rated at approx 200 watts per panel, so in your case you would need approx 250 x 200 = 50,000 watts of solar panels. Inverters are measured in watts, so if you chose a 50kw (50,000 watt) inverter that would be sufficient for powering the motor you mentioned. You would need 30 x 12v batteries wired in series to produce a nominal output of 360v dc. The size of the battery bank depends on how long you would like the motor to run for when there is no sun available to recharge them. It also depends on how many hours of sunlight you receive on average per day in your location and what time of year it is too. If we take 12hrs as an example then if your location receives 6hrs of sunlight per day then it would roughly take 2 days to fully recharge all 30 batteries if discharged to 100%. So that is about 15kwh of energy which is 50% discharge point for lead acid batteries and this is wise not to discharge more than half way down as they will hav shorter life span if discharged below 50%.
You need to know how many amps your motor draws per phase. The best way to do this is via a multimeter. There are many types of multimeters and they're not all created equal, so do your research before purchasing one. You can find them at most hardware stores or online.
Next you'll want to look up the recommended operating voltage for the motor in question (Vac). This is usually found on an electrical box or tag attached somewhere near the motor itself, or it'll be listed on documentation that came with your purchase. Next you'll need to take into account how much power you can generate from solar panels during daylight hours (or any other time), and multiply these two numbers together:
The amount of power you need to run your motor depends on the size of the motor and how long you would like it to run when there is no sun available to recharge them. For instance, if your motor is a 7.5hp three phase, then 30 x 12v batteries wired in series will give you a nominal output of 360v dc. The size of the battery bank depends on how long you would like the motor to run for when there is no sun available to recharge them.
The average solar panel is rated at approx 200 watts per panel, so in your case you would need approx 250 x 200 = 50,000 watts of solar panels.
The 7.5 hp motor consumes a lot of energy because it works on 3-phase power. A 3-phase motor runs at 400 Hz and each phase draws 1,200 amps. The total power consumed by a 7.5 hp motor will be (1,200 x 30) + (1,200 x 30) + (1,200 x 30) = 205 KwH per day or 469 KwH per week
The inverter is measured in watts, so if you chose a 50kw (50,000 watt) inverter that would be sufficient for powering the motor you mentioned. A 50kW inverter is a good size for that job and easy to install. The rest of the system depends on what kind of situation you're in and how much space/power supply is available.
For batteries to be wired in series they must have the same voltage. In this case, you would need 30 x 12v batteries wired in series to produce a nominal output of 360v dc.
If we were using lead acid batteries, then these should all be the same brand and have similar capacities (amp hour ratings). Once connected in this manner, if one battery failed for any reason, the other 29 will still supply enough power for the application at hand. This is another reason why it's best to use identical batteries rather than mixed brands or ages: if there's only one weak link left from an original string of 30, then you'd only have 29 remaining instead of 30 which could cause problems if too much power is drawn from them over time due to heavy usage or faulty wiring elsewhere in your system!

It also depends on how many hours of sunlight you receive on average per day in your location and what time of year it is too.
If your motor runs for 4 hours a day, then we recommend that you use the following table:
If we take 12hrs as an example then if your location receives 6hrs of sunlight per day then it would roughly take 2 days to fully recharge all 30 batteries if discharged to 100%.
Therefore, for a total of 30 batteries, you will need:
So that is about 15kwh of energy which is 50% discharge point for lead acid batteries and this is wise not to discharge more than half way down as they will hav shorter life span if discharged below 50%.
The solar panel array should be able to generate more than 3hp, but you need to check the capacity of your solar panels by calculating their total rating in watts. Then, multiply it by 1.5 hours (if you’re using a 7.5hp motor) or 2 hours (if you’re using a 10hp motor). The result will tell you how many hours can they run per day without having to recharge them.
