3kW solar system is a powerful system that can run household appliances. This solar system is capable to generate 3000W/h electricity. 3kW off grid system is the best fit for those who are looking for a complete sustainable energy solution for home including a battery and an inverter. This will allow you to run the appliances easily, but it cannot run the 2-ton air conditioner. Let’s understand more about 3 kW solar system.
Usages
Most of residential homes having Water Pump, Refrigerator, Cooler, TV, Washing Machine, Laptop, Lights, Fans, Iron Press, and more. The capacity of inverter needed for a 3KW Off Grid Solar System is 3KVA. As per expert recommendation, we run maximum load only 80% of inverter capacity. When talking about regular load of homes, then it will be up to 10% to 50%. As per 75% homes survey, we found a list of home appliances and their load required to run.
| Appliances | Power |
| 1.5HP Submersible Water Pump | 1500Watts |
| Refrigerator (Single or Double Door) | 200/400Watts |

Power Backup
3KW Off Grid System has Inverter Capacity: 2900Watts & Battery Capacity: 5800Watts. In this power backup system, we will run following appliances smartly.
| Load | Appliances | Backup Time |
| 300 Watts | Lights, Fans, TV, Laptop, Camera | 19 Hrs. |
| 1000Watts | Lights, Fans, TV, Laptop, Camera, Surface Water Pump | 6 Hrs. |
| 2000Watt | Lights, Fans, TV, Laptop, Camera, Submersible Water Pump | 3 Hrs. |
Note: We never recommend to run home load more than 80% of inverter capacity, otherwise, your power backup will be very less. When we run 50% loads of inverter capacity, our backup time will be 4 hours.

Best 3kw Solar Inverter in India
A solar inverter is central product of solar system and we can say it is brain. It controls all things such as input & output loads. You need to choose a solar inverter very carefully. We have written solar inverter buying also, you may refer that. If you have decided to install stand alone (off grid) solar system, then a 3kW solar inverter comes in 48V input voltage and 80%-90% maximum load capacity. You can connect 4 no. of 12V battery (normal battery or solar battery both) and 3000 watt solar panels.
Area required for 3kw Solar Panel?
An efficiency of solar panel is increasing year on year and currently the latest technology of solar panel’s efficiency is 22.5% or above. This efficiency of solar panel comes in 575W-700W in TOPCon Solar Cell Technology. A size of TOPCon solar panel is 7.5 x 4 ft = ~28 sq. ft. and weight is 32 kg. If you choose this solar panel then you need 5 no. of solar panel. That means, you need 146 sq. ft. installation shadow area where sun light comes at least 7-8 hrs. per day. If you choose less wattages of solar panel such as 440W, then installation area will be increase such 160 sq. ft.
What can i run on a 3kw solar system?
3kW solar system has 48V MPPT Based Solar Inverter (PCU) and you can run 2500 Watt maximum load on single time. But, if you calculate maximum power consumption of house, then it will be very maximum. Don’t follow this calculation. You need to calculate regular power consumption of your home. If you check trend of power consumption in your home, then you will get morning and night time will be high and noon time will lower. Generally, 40% power consumption of 24 hours is in day time and 60% power consumption in night time. We recommend to follow AMG formula to adopt solar power.
What does a 3kw Solar System Produce?
The generation of 3kW solar system is 15 – 18 units per day and a solar panel works 300 days out of 365 days in a year. That’s means, 3kW solar panel generates 4,500 – 5,400 units yearly. But, it depends on solar panel technology, climate, power consumption, system type, service and maintenance. National laboratory of the U.S. Department of Energy (NREL) has developed a tool to know solar panel generation of any location. You may use this tool.
How many solar panels for 3kw inverter?
You can connect up to 3000 Watts solar panel with 3kW inverter. The main difference between normal inverter and solar inverter is Solar Charge Controller. Normal inverter has no option to connect solar panel but solar inverter has option to connect solar panels. Solar Inverter has categorized into different voltage rage such as 12V/24V/48V/96V/120V and different capacity such as 1kW/2kW/3kW/5kW/7kW/8kW/10kW. These inverters come in off grid solar inverter which works with batteries.

FAQ...
#1. I have a 1hp water pump, 3 ceiling fans,1 stand fan,190 L freeze,1 Usha wall fan,10 cfl of 20w each. Suggest me for the best mono perc solar panel, battery and inverter for that. Plus, prices for that separately.
Ans: First calculate total home load, such as: 1HP water pump (700 Watt) + 3 Ceiling Fans (150 Watt), 1 Stand Fan (50 Watt), 190L Freeze (100 Watt), 1 Usha Wall Fan (50 Watt) + 10 CFL (200 Watt) = 1250 Watts. Your maximum power consumption of your home is 1250 watts, here you should install a 3kW solar system to run all appliances without electricity. The 3kW Solar system has 6 super high efficiency solar panels introduced by LOOM SOLAR, 3000 watt hour lithium battery, and 48 v mppt solar inverter (PCU). Along with this system, a balancing system, such as high-rise panel stand (6 ft. height), dc wire (6 sq.mm.), dcdb & acdb, lighting arrester, earthing kit, etc. Buy Now

Hello dear sir
In my house all ready got 3kw system still my electricity up I won upgrade that system end same loom company I installed in vadodara tandalja gam I just need information about is any installment system if I won upgrade 5kw end any subsidiary come if I upgrade

Can I directly charge my EV car with Solar DC batteries and use it only for my single phase lighting requirements with an inverter. As the wiring is different for AC, Geyser, and Refeigerators, they can run in utility power. So I need a off grid system that can charge my car and my single phase lighting (mostly LEDs), what will be the cost for 3KW system?
