Company Info

APsystems was founded in the USA's Silicon Valley in 2009 by Dr. Zhi-Min Ling and Yuhao Luo under the name APS. After establishing a manufacturing facility in Jiaxing, China, the firm released its first product in 2010, a dual-module microinverter.

The company opened a sales office in Sydney and an office in Shanghai in 2011 to service the APAC region. In 2015, APS rebranded as APsystems.

APsystems listed on the Shanghai Stock Exchange in June 2022, and by the end of that year had surpassed 3 gigawatts in cumulative product shipments. Today, APsystems is headquartered in Seattle, USA, and Jiaxing, China. The company serves customers in 120 countries and claims over 5 GW of products shipped; including approximately 4 million microinverters.

APsystems Microinverters

The company offers a number of microinverter solutions, including the DS3 (single-phase) and QT2 (three-phase); as well as their APstorage products, such as the ELS-5K PCS.

DS3 Single-Phase Microinverters 

The dual-module DS3 model series available in Australia offers 625, 750, 880 or 960 watts output and is fully backwards compatible with APsystems' QS1 and YC600 microinverters and accessories (which have been discontinued in Australia). 

The DS3 features 2 input channels, each with an independent MPPT, and encrypted wireless Zigbee communication. They have an operating temperature range of -40°C to +65°C

QT2 Three-Phase Microinverters

QT2 series is APsystems' second generation of 3-phase microinverters; supporting four solar panels and providing power output of 2000VA to suit today's larger PV modules. With balancing 3-phase output, 4 DC inputs and encrypted ZigBee comms, the QT2 features an entirely new architecture. According to APsystems, it provides 97% peak efficiency with 20% less components compared to the company's previous generation product.

ELS-5K PCS Battery Inverter

A full size inverter but based on APsystems' MLPE technologies, the ELS-5K PCS 5kW unit offers a modular, single-phase AC coupling energy storage solution for residential solar. It offers multiple modes including backup power supply, self-consumption, peak and valley, and peak shaving. The ELS-5K has a UPS-level switching time of <10ms. 

The ELS-5K inverter supports parallel connections and is compatible with various batteries, including selected models from Dyness, Pylon and of course, APsystems' APStorage products.

APsystems' microinverter and inverter monitoring is via the company's EMA App. It allows (near) real-time performance tracking; with system output by day, month or year, energy savings and environmental benefits.

Warranty Information

APsystems microinverters are accompanied by a standard product warranty of 10 years (which can be extended for a fee), which begins on the earlier of three months after the date of the shipment of the product from the company or the date it is registered in the EMA portal. But note products purchased after Jan 1, 2021 not continuously connected to the internet only have a warranty of 2 years, starting from APsystems' shipment date.

The ELS-5K inverter comes with a ten-year product warranty.

APsystems Solar Inverter Reviews

Only reason for not giving 5 starts is because some of the inverters failed. Technology can fail and I am not judging APSystems.

So over the last 7 months we have saved only $230 of our electricity bills so if we save $300 a year and our solar panels cost $7900 it will take 26 years to pay for itself and we would probably need new panels before then. Not worth it wish we didn’t do it.

Great performance of the system throughout the day with one inverter on northern roof, one inverter on eastern roof and one inverter on the western roof.

The inverters do not operate all the time

Constantly have problems with these inverters not being able to be connected to the wifi, show up as NC- not connected.
System is less than 12 months old and have had to have 4 inverters replaced with a huge lead time on the repair,
i do not recommend this product at all- wish i went with Solar Hart

I have installed a 9 kw system with 36 panels and mini inverters. So far I had to call the installer back 3 times and he had to replace 3 panels an one inverter inn the past 3 years. Now I have 2 panels that are not working and I was told to contact aps directly for which are not contactable as the NSW contact number being the Australian he’d office rings out.

We have micro inverters so far so good.

My system is using APS microinverters (i.e. AC current with an inverter under each panel). Since installation I have been getting consistent performance across all 8 inverters/panels throughout the year, with performance being easy to monitor online directly through my WiFi internet connection and real-time 24/7 monitoring. It is a very well-installed system that has been subjected to all types of coastal weather over the past year and shown no variation in performance whatsoever. A winner!

It is unknow if they are actually working. After trying to track down someone to come and have a look- (we have a 30 year warranty) Apparently unless the digital display box which can be remotley read but has stopped working can not be accessed they can not confirm they are Not working therefore it will be at our expense for someone to come and see if they are working...round and round we go, unhelpful.

One of the micro inverters stopped working within a couple of months of installation. Unfortunately we were away for 3 months at the time and didn't know about the problem until we returned, which wasted a lot of energy that would have been exported into the grid. We were told by the salesman that our system would be monitored and any problems would be flagged and fixed within a couple of days. This was clearly not the case! Due to the fact that we returned at the start of December, we had to wait until the next year to have it fixed. Other than that, they seem to be working well.

The contraption the company to test the inverters is too complicated for me to operate, but based on the power bills they seem to be working OK, instead of 300 dollar bills we get 180.

Initial interference was experienced with our TV reception during daylight hours. 2 attempts were made by the company to fix this. The second being most effective due to the installation of an extra TV aerial tuned to Gippsland channels. We were not charged for this work.

Great that it allows each panel to perform to the best of its ability given shade etc and that you are able to monitor it all online.
Bought From: SolarMyHome Show additional information
I've had 2 failed micro inverters which were replaced by the supplier (Sunwise). With a 5KW system I imagined all my electricity usage would be covered. However, I find that even on full sun days (in Winter) the max it puts out is about 3KW and about 1KW on cloudy days, leaving me with an electricity bill to pay. Maybe my expectations were too high for this system

They seem to work fine... not sure what else to say :-)

We chose a microinverter system. One of the ten inverters 'cooked' itself about three months ago ( our system has been installed for less than a year) and has been replaced under warranty by the installers. The technician said that he had not seen one of these inverters fail internally before - not an ambient temperature cause. Otherwise they seem to be working well.

We have 6 of the APS-YC500 micro-inverters in operation now for about 9 months. These micro-inverters appear to produce an output proportional to the available panel exposure under the variable shading conditions we have experienced during the winter months, right down to completely shaded. As far as I can tell, this is making good use of the available sunlight under these variable shading conditions.
The remote monitoring provided by these inverters in conjunction with the ECU control unit and the manufacturers website, provides a very useful tool for online monitoring of the system performance in real time for the whole system, or panel by panel, or the entire historic record by day/week/month/year (provided the ECU control unit has internet access). It is also supposed to report individual panel or inverter failure immediately - but no failures yet so I can't comment on this.
