Growatt vs PowMr vs Temank vs Ampinvt solar inverters

Growatt vs PowMr vs Temank vs Ampinvt solar inverters

In this post we will perfrom a detailed comparison of 5000 watt off grid solar inverters from four renowned brands namely Growatt, PowMr, Temank and Ampinvt.

Solar power is a clean and green source of energy. When the sun shines, it heats water, which in turn produces electricity that can power a variety of machines. In many cases, homes, businesses, and other buildings use the excess heat from a sunny day to create electricity.

Different companies are making solar inverters like Fronius, Solar Edge,Huawei,SMA,Sungrow,,Fimer, Delta but from all those we will compare only these four brands at a minute level.

How much power Solar inverter I need

This is a very critical question and its answer depends on the number of electrical devices you use. First of all you need to know how much power is consumed by each device. For example the power consumed by some of popular devices is like that.

Coffee maker (1000W), Microwave (1000W), Toaster (1200W), Refrigerator (1200W), Computers (150W), TV (250W)

Now you can find the power consumed by different devices from here. After that you add all of them to find the total power of inverter you require. But make sure you add only those appliances in the list that are running all the time or most of the time.

Important for United States Customers

According to our team suggestion you should not buy European or International inverters in United States. If you are Unite States resident you should keep in mind that buying an inverter can be a bit tricky and you can easily lose almost 1000 dollars and you may end up wasting your time and money. Most of the inverters on sale are 240 volt like Growatt and PowMr but in United States these will not power your house unless you have a transformer. The transformer actually adds a neutral to the line. Growatt and Powmr and other such brands are quite successful in European countries.

Growatt has a specific version for United States called Growatt SPF 5000 US. If you are going to buy European version, you may require their product called AutoTransformer.

Where to buy from

As most of these inverters are mostly of Chinese origin, so I suggest that you should buy them from Amazon so you get at least 1 year warranty.

Growatt vs rest of brands

What makes Growatt different from other brands (PowMr and Temank) is that they can join together to give more power. This means that if you purchased a 5000 watt inverter and you need 10,000 watts of power you just need to purchase another inverter of 5000 watt and they will work together to produce 10,000 watts of power.

Charging modes comparison

In Growatt, PowMr and Temank inverters there are 4 modes for charging the battery. However, in the AmpInvt inverter, there is one more option which is called generator mode. In this mode, the generator is connected to the AC input of the inverter, and the output is stabilized through AVR while the battery is recharged.

In all the three inverters there are four modes for battery charging given below

  1. Solar first: Solar energy provides power to the loads as first priority. If solar energy is not sufficient to power all connected loads, battery energy will supply power to the loads at the same time. Utility provides power loads only Solar energy is not available or the Battery voltage drops low-level warning voltage.
  2. Utility first (default): Utility will provide power to the loads as first priority, Solar and battery energy will provide power to the loads only when utility power is not available.
  3. SBU priority: Solar energy provides power to the loads as first priority, If solar energy is not sufficient, the battery will supply power to the loads at the same time. The utility provides power to the loads only when battery voltage drops to low-level warning voltage.
  4. SUB priority: Solar energy provides power to the loads as first priority, If solar energy is not sufficient solar and utility will power loads at the same time. The battery provides power to the loads only when solar energy is not sufficient and there is no utility.

Where we can add a solar inverter

For homes and businesses that are built in areas with enough sunlight, solar power can be an affordable and environmentally friendly way to generate and consume energy. Inverters are solar power devices that convert the sun’s energy into direct-current electricity. They do this by converting the sun’s heat energy into direct current. Thus, inverters are solar power devices that convert the direct current produced by a solar power system into electric power, which is distributed to the electric grids.

Current produced by inverter

Solar inverters are energy conversion devices that convert direct sun power into alternating current (AC) or direct current (DC). The main purpose of a solar inverter is to convert the current from the sun into the home’s electrical grid. Most homes don’t have a generator but rather rely on the electrical grid to supply their homes with electricity. Because of this, most solar inverter products are electric generator-oriented. However, there are a few exceptions such as the Inverter Solar Inverter. This product is a portable solar inverter that can be used anywhere there is an electrical power line. Read on to know more about the features of this product, its advantages over other inverters, its disadvantages, and our recommendations.

Off grid solar inverter

Off grid solar inverter is a small and simple device that converts the direct current (DC) output of a solar panel into alternating current (AC) suitable for use in homes and businesses. However they cannot send the current to the National grid but they are good enough for home use. Offgrid solar inverters are available in different sizes and operating voltages to suit a wide range of applications.

The electricity produced by off grid solar inverter is usually stored in Lithium deep cycle batteries.

The two most common types of offgrid solar inverter are the DC-DC and the DC-AC. They differ in their type of conversion. The DC-DC inverters simply substitute one form of direct current (DC) for another. The DC-AC inverters use an AC generator to produce the same voltage as the DC output of a solar panel. They differ from each other by the method used to convert the AC output to make sure it is suitable for use. For example, the AC-AC inverters make sure that the frequency of the converted output is the same as that of the AC wall socket.
