Solis Inverters UK - Bootle

My Solis Inverter keeps tripping the ring-main RCD and comes up with a fault code OV-TEM. Un-Surprisingly it means over-temperature! I’ve telephone their Liverpool service phone number three times and have been promised a call back………which never comes! DREADFULL Customer Service for a product under Warranty and conscious dismissal of a potential fire Hazard - I can only take them to the Small Claims Court for the value of a replacement Inverter + fitting and hope the house doesn’t burn down in the interim as my claim will increase somewhat.

One star only because I can’t give them zero stars!

Poor quality products with very poor service given during warranty. One of our 60kw invertors failed after just over 1 year’s use. Our installer has been chasing to get a replacement under warranty, service is slow to respond and stated the invertor is out of stock and gave no date when a replacement will be sent. There are over 50 new 60KW invertors in stock at the original wholesaler that the invertor was purchased from! The process has been going on for over 3 weeks now with multiple forms to fill out and multiple business days before any reply's and still no resolution.

I understand from the engineer who contacted Solis UK concerning an ongoing problem with a battery and converter installation on my property, that their response has been “let the customer just keep restarting the system”. A despicable and concerning response from any company, let alone a company concerned with this type of electrical installation. I understand from further investigation, that their products are getting a name for being unreliable and their customer service is becoming increasingly ridiculed for it’s lack of engagement and professionalism. I would recommend that any prospective purchasers of inverters or related equipment really do consider their options carefully before using Solis UK equipment.

I had a solar pv system installed with a Solis supplied inverter in July 2022. The system had worked well until the 6th March when the inverter failed. I contacted the installer of the system to inform them of the fault.

The installer sent an electrician to investigate, but he could not get the inverter back on, and felt that it would need to be replaced. I have been back and forward with the installer since the 6th March, and they have been pushing Solis to deal with this warranty claim, as the inverter is only 8 months old.

At the point of writing, my system has been offline for 17 days, and Solis have given my installer no information whatsoever as to a timescale for rectifying this issue. All they have said is that they won't honour the warranty if my supplier replaces the inverter without them 'investigating' it. But as I have mentioned, they have given no indication that they have any plan to investigate. This leaves me with an expensive, but useless solar PV system during this period of high energy costs, and unable to take advantage of the longer days, and increased generation potential, with no timescale as to when it will be restored.

This should be a warning to solar PV system suppliers to be sure they know what they are getting into, as the aftersales service from Solis has been nothing short of terrible.

Fitted in 2015, lasted 9 years. Should be built to last much longer. Apparently there are really really cheap relays in these that burn out. Probably reduced the manufacturing cost but Id rather have them charge a higher price and not cut back on reliability. Just shows what the company is like.

Very recently installed Solis S6 inverter showing alarm problem and batteries not discharging at all .
As the customer /end user Solis were unable to assist me personally .
But that is not really my gripe .
Seldom in life have i encountered such poor comprehension and such a bad manners ,i accept we have a little language barrier which makes things more difficult , but the rudeness of the so called Solis service operator was frankly pretty disgraceful , ya spends ya money and it doesnt work ...Tough !!
UPDATE
Just had conversation with another guy from Solis "Eric "( again perhaps English not his native tongue ) but what difference , polite , helpful ..Problem solved ...Thank you Eric !
