Terrible customer service.

PS: You will need to configure your system correctly in order to use your EV Charger for manual RFID or plug & play charging. Until you have done this then you cannot use these functions, this is not a fault with the product but an user error.

This is the message I recieved, but no where in the instructions does it tell me how to do this. The phone line is constantly engaged as well.

Risposta di Immersun

We understand your frustration and appreciate your feedback. The EV Charger does require an initial setup to enable all functions, including RFID and plug & play, and we always aim to provide clear instructions for this process.

If you haven’t received the necessary guidance, we’d be happy to assist. Please contact our support team via support@immersun.co.uk so we can walk you through the setup step by step. We’re here to help and ensure you get the best experience with your charger.

Don't go there.

I purchased this immersun diverter in Sept 2022 to replace my previous immersun unit. This has now failed but at the time of purchase, I believed it came with a 3 year warranty, not true. Having spoken to their agents today they did offer to come out and try to repair the unit for £189.00 but, with no guarantee of a fix. My advice look elsewhere, there are better options available.

Risposta di Immersun

We’re sorry to hear about your experience. Just to clarify, our standard Immersun power diverter warranty is 12 months, not 3 years, and this information is clearly stated at the time of purchase. As your unit is outside of its warranty period, we offered a repair service, which includes inspection and a professional attempt at fixing the issue. We’re always upfront that, due to the nature of electronic repairs, a 100% guarantee of success isn’t possible.

That said, we’re always happy to explore options to support our customers. If you’d like to discuss this further, please reach out to our support team, and we’ll do our best to assist.

Helpful Customer Service

You often find that post purchase customer service can be poor. I was therefore really pleased with the speed and helpfulness of their staff who helped me problem solve my 14 year old immersun unit.

It turned out that the immersun was working fine but there was a fault with the immersion heater linked to it.

Thank you

I thought the machine was broken

I thought the machine was broken, but ask the question and write what you see, the answer came back quick as a flash, dead easy instructions to follow on a handful of lines and low and behold the machine started to smile once again. Brilliant, just like the company who came up with the idea of keeping the electricity that you produce for your benefit.

Well done Anish M. my friend at IMMERSUN.

Upgrade of the PowerDivert 2.0 to 3.0

I bought the PowerDivert 3.0 to replace a very old and failed PowerDivert 2.0 from my original solar installation 9 years ago. The after sales support by Anish to integrate the 3.0 unit into the existing wireless installation was excellent. The price and delivery were also excellent.

Historic daily, monthly and yearly total reads

Had this Immersun device for many, many years with the odd glitch here and there (usually an outage) . Just wish they could give a full total daily, monthly and yearly read like they used to do. Bit of an irritation having to tot up each daily read on the historic graph to get a total monthly read for generation, export, diverted and imported electric.

Buyer Beware

IMMERSUN,

I received your reply to my review dated 22 July 2024,
First of all you go off in a rant about how your products come with a 12 month warranty and this is clearly stated, At no time did I state the product had a longer warranty, The point is it is expected to far out last the 12 month warranty,

You say you are proud of the quality and durability of your power inverters and "built to last" You should try a career change to comedy, I am in possession of 1 of your power inverters that completely rubbises your claim & in fact the company who supplied my solar system has informed me they no longer supply any of your products because of these issues,
If you are so proud of your products you should have offered a good will replacement, however, it's all about the money isn't it Immersun,

Under UK statutory rights CRA 2015 I am protected as a consumer I have 6years to take you to the small claims court and reclaim the cost of the repair,
I am a long standing member of Which, consumer champion & they are steering me in the right direction,

I stand over every thing I stated in my first review & my advice to potential customers is do not buy from Immersun,

Very Poor after sale support

Very disappointed with Immersun after sales support. I bought my first Immersun unit when I installed the solar panels in 2013. The unit failed in August 2022. I was offered the option to return for repair, but considering the age (9 yrs!) I decided to purchase a new unit instead (£499). This unit failed in April 2024, after only 20mths! An automated reply from 'support' advised me to run a 'reset' process on the device, and have the heater tested. The reset procedure made no difference, and the heater tested Ok. I advised support but got no reply!. Be warned this product only comes with a 1 year warranty!

Dear Mark,

Thank you for sharing your experience. We regret that you are disappointed with our after-sales support. The Immersun units are designed to last, as evidenced by your first unit's 9-year lifespan. We're sorry the new unit failed after 20 months.

While our warranty is one year, we strive to support our customers beyond this period. Please contact us directly to resolve your issue promptly.

Responsive Service

I inherited an Immersun (with little info from the previous owner) when I moved into a new home 18months ago. Everything worked smoothly until a recent incident. Once I’d established contact (my web browser security didn’t like the contact form) the feedback was quick and relevant. Problem not yet resolved as I have to go away but when I return I’m going to start taking more of an interest. Would have been a 5 star review but tried to use the chat bot first- which was pretty useless.

One year warranty

Very disappointed with the response from Immersun. I had my first unit for approx 7 years. September 22 it failed and after contacting Immersun they said that they had a new version and that it was significantly better so I purchased it for £500. It worked well until 2 weeks ago when it failed - just 20 months old. Immersun said I could return it for £180 but could not guarantee that it would be fixed. They said the alternative was to buy a new one as they had a new version out which again was even better. I queried the warranty and was told that it had expired by 8 months - so just a year warranty. Checking the warranty of the iBoost is 2 years and cheaper and the Solic (British made) has a 10 year warranty and is half the price of the Immersun.

No attempt to deliver DPD driver told fib

Not delivered by DPD but the courier stated that I would not take the delivery problem is they never tried to deliver I never had the choice to except or decline the delivery and Immersun when I informed them stated that it was for me to sort out. I emailed DPD and no surprise I still have had no response . Had an electrician had ready to fit the unit and now still trying to get it fitted. Legislation as I have had it explained to me is contact Immersun I'm buying from them not chasing DPD error.

Dear Customer,

We regret to hear about your recent experience with DPD's delivery service. It appears that this issue is primarily with DPD, as they claimed an unsuccessful delivery attempt. We advise that recipients first attempt to reschedule with the courier, as this is the standard procedure.

However, we are willing to assist you in resolving this matter. Please contact us through our support platform, contact us page, or via email at support@immersun.co.uk so we can help facilitate a resolution.

At last an EV charge point at a reasonable price.

At last an EV 7kw charge point with all the safety features required at a reasonable price.
Delivered a day after order. Well packaged.

Easy to fit, the pitch of the fixings of the mounting bracket match the mortar course of brickwork in my garage and the anchor bolts supplied ensure a good grip even in a "sloppy" hole.

The wiring of the charger can be done off the wall before it is slipped on to the mounting bracket and secured by finger bolts. No pesky earth rod required!

Couldn't be easier. Well done Immersun.

Now connecting to Wi-Fi and the app - well who reads the instructions?

When I did read the instructions and followed them pedantically, as in my third go, then I was able to control and monitor the charger on my phone. Top tip - read instructions carefully.

Charger (EVSE for the purists) installed 6 weeks now. Informed DNO of fitting, OK to use.
Charged car using push button on/off, swipe cards on/off but mostly using the app to set charge time to take advantage of Octopus Go night rates.

All good.

Ps. My wife said it looked nice but I need to tidy up the garage.

EV charger Fitted and up and running…

EV charger Fitted and up and running smoothly so far. The charger arrived next business day and was a doddle to set up once my electrician had installed it.

The electrician was impressed by the cost at less than half the price of major brands but with all the same functionality. What’s not to love. The instructions supplied are a bit chinglish and could do with a review.

Impressed so far.
