I am a distributor or installer of SolaX. How do I contact you?

Please visit our contact page for more information. We have a number of international offices offering regional services, or alternatively you can contact our global office.

What information with the technical support line require when I make contact?

This can vary from country to country, but as a minimum, you should have the product serial number and model details to hand. If your enquiry concerns the WiFi monitoring, you should also have the datalogger serial number – both serial numbers are shown on the side of the inverter. Depending on the country, you may be required to contact the support line while from site so that a proper diagnosis can be carried out, and a decision as to whether an inverter should be replaced under warranty can be made immediately. In some countries and territories, you may also be asked to provide an installer reference number.

I am an end-user, who do i contact in the even of a fault or if i have a question about my system?

Your first point of contact should always be your installation company. We offer service and support to our installation partners who in turn offer support to their customers.

Where can I buy SolaX products?

If you are a distributor, wholesaler or installer, please refer to our contact page for details of our local international offices. Many international markets are serviced directly from our global HQ, so if there is no regional office in your country or territory, please contact our global team and they will be happy to assist.

If you are an end-user and you are interested in SolaX products, we can offer advice and answer any questions you may have, however to purchase goods you will be referred to a local supplier/authorised dealer.

Product & Installation

What certification do the SolaX products have?

You will find certificates, documents of compliance and declarations of conformity in the certification area of this site. Click on the corresponding country to find the relevant downloads.

How reliable are SolaX inverters?

With ageing time over 24 hours, our inverters comply with the latest VDE-AR-N 4105 standard requirements. It’s MTBF trouble-free operation time is more than 100,000 hours and Total Harmonic Distortion (THD) is less than 1% which is the best performance in comparison to similar products. Moreover, our products have passed the authentication of SAA, CE, AS4777, AS3100, G83, VDE, CSA, FCC, ETL, CQC, ENEL Guide and RD1663.

Do you offer remote system monitoring?

Yes. We offer remote monitoring on all our products, but the platform used may differ depending on the model and age of the inverter. For more information about our new ‘Pocket WiFi’ solution, visit – http://www.solaxpower.com/en/wifi-monitoring/. Please refer to the relevant product datasheet for connection options.

Do you offer a sizing tool?

Yes, our sizing tool is an online resource and can be accessed for free here: http://design.solaxcn.com:6180/design/

The solar module i am using is not listed on the sizing tool, can i add it manually?

The module database is continually updated, however if you cannot find the relevant PV module you can add it manually by accessing ‘Settings’ and selecting ‘Administer my modules’ and enter the appropriate values. Please note that the table must be filled in completely. Click OK to save your entry. The module is now available when you design your layout with SolaX Design.

Are SolaX inverters suitable for installation near the coast?

Yes. During the development of our inverters comprehensive tests have been carried out. The housing, cover, cover seal as well as the connection components undergo salt spray tests in accordance with EN 60068-2-52. Our inverters are designed to be installed in areas with adverse environmental conditions. Amongst other things, the high protection class of the inverter contributes to this. This very demanding test is not a standard part of the CE examination and is carried out voluntarily by SolaX.

Do Solax inverters emit noise?

SolaX inverters fulfill all the regulations and specifications that apply to them and are well below permissible thresholds.
Unfortunately, the conversion of direct current into alternating current is not completely silent. Therefore SolaX does not recommend installation directly in a living area. You will find further information on the requirements of a suitable installation location in the installation manual which accompanies every inverter. In periods when the inverter does not feed energy into the public grid, (if the solar irradiation is not sufficient or during the night hours) it switches off and disconnects itself completely from the grid. In this state, no noise or electromagnetic radiation is produced whatsoever by the inverter.

The noise emission < 40 dB –Hybrid Single phase without fan makes little noise < 25 dB Three phase with fan < 50 dB

Can EMC disturbances occur during the use of SolaX inverters?

SolaX inverters fulfill all the regulations and specifications that apply to them and are well below permissible thresholds. SolaX also certifies this in the declaration of conformity which accompanies every inverter. These are DIN EN 61000-6-3 (2002) for emitted interference, DIN EN 55014-1 (2003) for grid-bound (DC), DIN EN 55022 (2001) class B for grid-bound (AC) and radiated, and DIN EN 61000-6-1 (2001) for immunity to interference. Aside from the regulatory requirements, independent analyses has shown that the requirements of structural biologists are fulfilled even as close to a solar system as one meter away. The electromagnetic radiation of an inverter is no stronger than that of a commercially available household device (e.g. hair-drier or fridge).

Who can install SolaX inverters?

Only professional technicians qualified to install PV and battery storage systems in their relevant country/territory are permitted to install SolaX products.

Do you offer installation training courses?

Yes, but this does vary from country to country. The installation of our grid-tied, string inverters does not require specialist training. However, we strongly recommend that installers contact us before attempting to install their first Hybrid inverter (with batteries). in some countries (the UK for example) we offer a ‘Premium installer’ programme that requires engineers to attend a one-day course focused on the correct installation and configuration of our X-Hybrid range. Below is also a video demonstrating the installation of our X-Hybrid:

Monitoring Questions

Do you offer remote system monitoring?

Yes. We offer remote monitoring on all our products, but the platform used may differ depending on the model and age of the inverter. For more information about our new ‘Pocket WiFi’ solution, visit – our wifi information page. Please refer to the relevant product datasheet for connection options.

How do i set up remote monitoring?

Please refer to the set-up manual provided. Alternatively, you can find video guides at the bottom of this page.

What is the maximum Wi-Fi range?

There is no defined maximum. Any WiFi connection is subject to range restrictions – and these can be influenced by a variety of eternal factors. To test whether WiFi connectivity will be possible prior to install, try standing in the location where the inverter will be installed and use a smart phone to see if it can see the customer’s WiFi signal (but this is not a guarantee and should only be used as a guide).

Do I have to use Wi-Fi for system monitoring?

No. For certain products within our range there are a variety of connection options. Our X-Hybrid inverters allow for direct connectivity between the inverter and router using an ethernet cable. This may not be practical in some instances, so an alternative might be to use a device such as the TP-LINK Powerline.

Monitoring is also available using a Smartphone or tablet using the app in ‘local mode’ – however it will not be possible to monitor the inverter remotely with this option.

Is WiFi connectivity covered under warranty?

No, however if the inverter has an internal WiFi adapter, it will be replaced under the exchange programme if it is proven that the WiFi adaptor is faulty. If the inverter is emitting a WiFi signal but no data is being received to the cloud, then this will fall outside the terms of the warranty. The WiFi connectivity is subject to external factors such as range, and relies on the correct configuration of third-party devices such as routers, factors that are beyond the control of SolaX.

Our latest product range is supplied with an external ‘plug & play’ WiFi adapter which will be replaced under warranty if proved to be faulty.
