Home solar inverter… Nowadays, solar inverters are deployed in many homes, industries, factories, etc. Solar inverter is an electronic device that converts Direct current power into alternating current power. One thing I always tell people is never to participate in what you have no idea about as regards electricity.
Electricity is dangerous when it’s managed carelessly. Let’s say you are facing a challenge or you had experienced a challenge of how to size your solar inverter. Then, this article is here for you. It has all the reliable solutions to your worries.
In addition, this article contains other related solutions that will make your day an information full day. These include [What factors should you consider when sizing a solar inverter? What size inverter do I need for 5kW solar system? How much load can a 5kVA inverter take?].
I urge you to relax and keep reading. All the information as regards the subject matter is here.
HOW DO I CHOOSE THE RIGHT SIZE INVERTER ? HOME SOLAR INVERTER
Solar clients always ask how to choose a suitable inverter capacity. In practice, it is good to check and select the correct inverter with the right power size.
However, you will overload your inverter if you fail to consider the appropriate inverter capacity that will suit your loads.
Below are a few steps to take before you conclude on the inverter size you should deploy.
Firstly, you should know the difference between KW, KVA, and KVAR.
Step 1: Take note of all the appliance power ratings in watts or kilowatts. Let’s say you have 4000 watts in total.
Step 2: Convert the real power watt to apparent power VA
- Real power =4000W
- Power factor= 0.9
- Apparent power VA = Real power/power factor
- VA = 4000/0.9 = 4,444VA approximately 4,500VA
- Convert VA to KVA, 4500VA/1000 = 4.5KVA
In like manner, you should deploy a 4.5KVA or 5KVA inverter for a 4KW load.
WHAT SIZE INVERTER DO I NEED FOR 5KW SOLAR SYSTEM? HOME SOLAR INVERTER
Inverter size depends on the total loads you wish to energize with your system. Furthermore, the 5KW solar system refers to the solar panel array power. The solar panel power is directly proportional to the battery bank capacity.
On the other hand, an inverter rating is directly proportional to the available Loads. You can decide to deploy any inverter size on a 5KW solar system. Do your load calculation, and then you can decide on the best inverter rating for the loads.
HOW MUCH LOAD CAN A 5KVA INVERTER TAKE?
This particular question has pulled some solar installers’ legs severally. But I am here to give you the precise answer to it.
Below are steps to decide on the load a 5KVA inverter can withstand.
- convert from apparent power KVA to real power KW.
- power factor = 0.9
- Real power KW = Apparent power x power factor
- KW = 5 x 0.9 = 4.5KW load.
NB: To prolong your inverter life span, I advise you to keep it loaded always below 70% of its KVA rating.
