When you propose to put in photo voltaic panel, battery and inverter, you then should be questioning about find out how to resolve the capability of those elements. On the idea of our sensible expertise, beneath information will enable you to.
Step 1: Load Calculation
The greatest option to calculate load calculation is to make use of very best quality clamp meter. Let’s assume for this calculation we’ll use a clamp meter that may help 600A . Using this clamp meter, we are able to calculate energy consumption of dwelling, workplace, store, college, medical clinic, & petrol pump, and so on. Follow the beneath steps to Calculate the ability consumption:
- Turn on all of the home equipment
- Use clamp meter in section wire of electrical meter
While you employ clamp meter, it reveals energy consumption in Amp. Such as 5Amp, 10Amp, & 20Amp, and so on. Indian grid voltage vary begins from 220V-240V. But you will need to verify voltage as effectively utilizing this clamp meter.
Load Calculation = 220V * 5 A
= 1100W
Step 2: Backup Time
In above steps, I’ve calculated the ability consumption. On the idea of this calculated energy consumption, we must always know what number of hours you might need to run home equipment after energy reduce. If your reply might be 4 to five hrs. That means:
Battery Storage = Total Load * Backup Time
= 1100W * 4 hrs.
= 4400W

Step 3: Battery Capacity
In above steps, You will find out about your required battery storage. There are two sorts of battery expertise in India – lead acid battery & lithium battery. In lead acid battery, 150Ah lead acid battery is the most well-liked battery for properties and companies. One 150Ah battery shops 1300 Watt. That means, you want
Battery Capacity = Required Battery Storage / Battery Storage
= 4400W / 1300W
= 4 Batteries
Generally, 4 batteries of 150Ah is available in 48V.
In case of lithium battery, you want just one battery that comes with 5kWh, 48V.

Step 4: Inverter Capacity
In above steps, you’ll know each the battery capability and voltage. According to battery voltage, capability, and energy consumption. In easy language, I want right here a 48V & 5kW inverter.
Inverter Capacity = Load + Load * 20%
= 1100W + 1100W * 20%
= 1100W + 220W
= 1320W
That means, you want round 1.3kW inverter capability.
Step 5: Solar Panel Capacity
Finally, it’s essential to calculate the photo voltaic panel capability. We all the time know that photo voltaic panels generates DC voltage (22V to 50V). In easy phrases,
Solar Panel Capacity = 3 * Battery Capacity
= 3 * 600Ah
= 1800Watt
That means, you want 1.8kW capability of photo voltaic panels and the best wattages of photo voltaic panels in India is round 540W. If you select these photo voltaic panels, then you have to round 4 photo voltaic panels for charging your battery in addition to run your private home masses.
