“What about monitoring?”
All our Solis inverters have low cost monitoring solutions which will be offered during checkout. All PV systems should include monitoring to avoid lost FIT revenue in the event of a fault.

“What about warranties?”
Your warranty is not affected in any way by DIY installation. Inverter warranties can be extended and this will be offered to you during checkout. Solis have UK based support and dispatch replacement inverters from UK stock. In the event that you believe there to be a fault we will assist you with the diagnosis. We may ask you to do some simple electrical tests as part of the process and if the inverter is at fault we will initiate a warranty claim with Solis.

“Do these prices include VAT and delivery?”
All our prices are fully inclusive of VAT and delivery to most of the UK. For Highlands and non-mainland, supplements apply which will automatically update during checkout.

“Can I really fit my own inverter?”
It’s a straightforward task for a competent DIYer. Click here for our guide.

“Should I buy a higher powered inverter so that it will last longer?”
Somewhat counter-intuitively, inverters should be slightly undersized to the solar panels to get the best yields. You can read more about this here.

This inverter has an integrated d.c. isolator and is ideal for installations which do not have separate d.c. isolator(s)

Tip: If each string of panels in your system are of equal length AND the panels are all oriented the same way AND there is no shading, you can use a Solis 3.6kW mini S6 Inverter as a lower cost alternative. However, the strings MUST be equal which MUST be confirmed with a voltage check. Contact us if you’re unsure.

    The new inverter was easy to install. Only had to fit a new mounting bracket for the inverter and change the plug on the AC isolator switch. Everything started working as soon as it was switched on.

    The Solis 3.6k S6 was a direct replacement for our dead Power One Aurora PVI 3,6 OUTD 3.6kw Inverter.
    Stuart answered all of my questions promptly, some even out-of-hours.
    Thoroughly recommended; we’re now ‘back on the grid’ and generating again!

    Read a previous review about replacement of Aurora One and was convinced. Stuart was great with updates and amazing DPD driver who worked way past his cutoff to make sure I got it. Fit was easy and exactly as described – Wi-Fi option over complicated but got there in the end. Great service – great item and glad I chose RedElectrical for the order – thank you everyone.

    Installed and, as advised, ideal replacement for failed 10 year old Aurora Power One inverter. Monitoring using WiFi stick and all is good. Easy to DIY install.
