If you are thinking of installing 3-kilowatt solar panels, you should first know what you can power with them. Generally, 3-kilowatt solar panels can generate approximately 15 units of electricity in a day (3 kW solar panel unit generation). If your daily electricity consumption ranges from 12 to 15 units, then 3-kilowatt solar panels would be suitable for you.
However, to set up a 3-kilowatt system, you have various inverters available. There are inverters with a capacity of 3kVA on which you can connect 3-kilowatt solar panels, but they can support a load of only up to 2kW.
So, this system is suitable for those who need to power loads up to 2kW daily, but it generates approximately 15 units of electricity daily. If you want to run both 3kW solar panels and a 3-kilowatt load simultaneously, then a 5kVA solar inverter would be the right choice.
What Can We Run On 3 Kw Solar Panel
If you install 3-kilowatt solar panels in an On-Grid solar system, which doesn’t use batteries, you can power loads based on the inverter’s capacity. In an On-Grid solar system, the inverter blends the power from your solar panels with the power from the grid to operate your home’s loads.
Let’s say your solar panels are generating 3 kW of power, and you are running a 5 kW load. In this case, the remaining 2 kW of electricity will be supplied by the grid, and your home’s load will be powered. However, this system won’t work during a power outage, and the power generated by your solar panels will go to waste.
If you want to install 3 kW solar panels on your Off-Grid solar system, the load capacity will depend on your solar inverter. If you choose a 3 kVA solar inverter for your 3 kW solar panel system, you can easily run loads of up to 2 kW at a time. Below is a list of appliances that you can run at different times with a 3 kVA solar inverter.
- 1.5 Ton Inverter Air Conditioner
- Ceiling Fan
- Cooler
- Tubelight
- LED Bulb
- Television LED
- Set Top Box
- Music System
- Laptop
- Desktop Computer
- Laser Printer (Small)
- Juicer Mixer Grinder
- Toaster (800w)
- Refrigerator (Upto 500L)
- Washing Machine
Here are all the appliances mentioned that you can run at different times. However, at any given time, you can only run a maximum load of 2 kW.
How many appliances can run on 3 kW inverter
If you want to know precisely what you can run on a 3-kilowatt (5 kVA) solar inverter, you’ll need to first determine the power consumption of all your appliances by using an energy meter. After calculating the power consumption of all your appliances, you’ll be able to determine which ones and how many you can run on a 3 kW solar inverter.
- 2 X 1 Ton Inverter AC = 2200w
- 2 Ceiling Fan (75w) = 150 W
- 3 Tubelight (20w) = 60w
- 2 X Television LED (100w) = 200w
- Laptop (100w) = 100w
- Refrigerator (200w) = 200w
Total = 2910w
So, you can run this much load simultaneously on a 3-kilowatt (5kVA) solar inverter, and most households primarily use these appliances.

Best 3Kw Solar Inverter
While there are several inverters in the market that support 3Kw solar panels, if you want to purchase an inverter at a lower cost, you should go for a PWM technology solar inverter.
If you prefer a high-quality technology solar inverter, you should opt for an MPPT technology solar inverter, which is slightly more expensive. Below, I have listed some PWM and MPPT solar inverters.
UTL Heliac 4000
This is a PWM type solar inverter that can handle loads up to 1kva. You can connect up to 3.2kw of solar panels to this inverter, suitable for loads of around 2500w.
They can use this inverter. By connecting 3kw panels to this inverter, you can create an excellent 3kw solar system. This inverter operates at 48V, so you will need to connect 4 batteries to it.
Price: Rs.25,000
Luminous Solarverter Pro PCU – 3KVA
Luminous Solarverter Pro PCU – 3KVA/36V is an MPPT type solar inverter that can handle loads up to 3kva. You can connect up to 3.5kw of solar panels to this inverter, suitable for loads of around 2.5kw.
You can create an excellent 3.5kw solar system by connecting 3.5kw panels to this inverter. This inverter operates at 36V, so you will need to connect 3 batteries to it.
Price: Rs.30,000
UTL Gamma 5kva
UTL Gamma 5kva is an MPPT type solar inverter that can handle loads up to 5kva. You can connect up to 5kw of solar panels to this inverter, suitable for loads of around 4kw*. This inverter operates at 48V, so you will need to connect 4 batteries to it.
Price: Rs.50,000
So, here you have two inverters that require 4 batteries and one inverter that requires 3 batteries. If you only want to install 3kw solar panels, you can choose either the UTL Heliac 4000 or the Luminous Solarverter Pro 3Kva inverter. If you also want to run a 3kw load alongside 3kw solar panels, you should go for the UTL Gamma 5kva solar inverter.
