Solis Inverters Review


If you’re an Aussie, you will know that only the best can last in our weather. So it should be no shock that Solis Inverters are now a big player in PV solar with the single Phase 1P5K-G4 5kw inverter and the Solis 3 Phase 3P5K-G4 inverters that we review here. It’s a tough game to be in, but Solis has the goals on the board. This brand on the move on the global stage, and so has made its mark here too. It has taken over 20 years of hard work to build a great PV inverter range. So what we have is something that you can rely upon to do the job, and keep on doing it.

Solis was in fact one of the first PV brands to come on to the Aussie market. So they have been at it a long time and should know what they’re doing. They are now up to the ‘Gen 4’ series that has both good looks and out put to match. There are so many points to list, just down load the data sheet and look it over. Yes, there are things you’ll see there that you know others have got but cost a lot more. They are all approved by the CEC so you can feel safe buying one of these too. Solis claims to have a working life of more than 20 years. So that's great news for Aussie solar buyers that don't want to spend too much! You can get them in both single and three phase, so there's bound to be one that suits you.

Solis 4G 5kw Inverter - 1P5k 4G

Single Phase - Solis-1P5K-4G

The Solis-1P5K-4G is a single phase inverter, and the one most commonly installed in Australia. This inverter features super high-frequency switching technology and an Optional 24-hour load consumption monitoring solution. It is also Compact, lightweight, and has an Integrated Export Power Manager (EPM) feature. The benefits of the 4G series include a maximum efficiency of 98.1 per cent, and the use of 2 MPPTs (Maximum Power Point Trackers), allowing for installing two solar panel arrays facing in different directions. WiFi monitoring is also available with the Solis 1p5k 4g and access to Android and Apple apps.

Solis 5G 7kw 8kW inverter

Single Phase (Solis-1P7K-5G,Solis-1P8K-5G)

If you're after a larger system, the 7-8kW Single phase string inverter series are ideal for most single-phase residential situations, nd have ultra-high switching frequency, ultra-thin single four-layer board design that can minimize the connector risk of Grid over-voltage.

This inverter is friendly and has an versatile connection to the power grid. It supports 1.1 times overload which increases power generation. The Solis single phase 1P(7-8kw)K-5G is lightweight at 13.3kg, and easy to install by a single technician. The IP65 protection rating, good for outdoor installation and WiFi monitoring is available from the Android and Apple app stores.

Solis S5 5kw 6kw inverter

Single Phase S5-GR1P(3-6)K

Another new entrant into the Solis single phase inverter line up, is the new S5-GR1P(3-6)K. This inverter has a 14 amp input for each string, So, this means that with the general move toward panels with higher amp output, more panels can be installed on a particular string. The inverter compensates and balances the input load accordingly. Most single phase 5kW inverters have an amp input limit of around 11-12 amps. So the S5-GR1P(3-6)K is another tool we can use in tight situations where we need to install a greater number of panels on one of the two strings.

Solis 5kw-20kw Inverter

3-Phase - 3P(5-20)K-4G

The Solis-3P(5-20)K-4G 3-phase inverters are suitable for residential, small industrial and commercial PV projects. These inverters are compact, with a maximum efficiency of 98.7%. The Solis 5kw-20kw inverter has a wide voltage range, too, is equipped for low startup voltage and has multiple protection levels. The 2 MPPT design with a precise MPPT algorithm gives more flexibility and is more efficient. Monitoring apps can be found on the iPhone/Android app stores, so you can watch your power production.

Solis Three Phase S5-GR3P5-20K

As with the the Solis single phase range of inverters, there have been other additions to the residential 3 phase range. Like the single phase S5-GR1P(3-6)K, which has a higher amp input than other models. The new 3 phase S5-GR3P(5-20)K-AU for residential applications, allows for an even greater, 16 amp string input. This allows for more flexibility of panel choice and system design while keeping a firm hand on efficiency.
