Very competitively priced, with helpful staff that knows their stuff. They went above and beyond to correct a mistake I made on my order. I will definitely be purchasing any future solar requirements from them. My only regret is not finding them sooner, I would have saved a fortune.

Fast delivery, competitive pricing

Purchased for campervan conversion , finally all wired up and connected works perfect , great piece of kit and good price

Works seamlessly with Solar panels & Pylontech RT12100 100Ah battery. Easy to monitor using the freely available Victron Connect App.
Would highly recommend the Charge Controller & Callidus who are always very helpful & informative.

Fantastic piece of kit. Does what it says on the box. Victron equipment is very reliable, and great to connect to smart phone.

Excellent quality product and great customer support service always happy to help and provide support

As always it does what it says on the tin and has never let me down. Love victron stuff, easy setup and forget.

Have now brought 3 lots of solar from Callidus and every time have been perfect, fast deliveries and helpful communication, easy to install with no problems, can’t praise them enough,

It’s my second victron charger, and most likely I won’t go any larger than this. It’s responsible for charging a 150 amp 51.2v

Absolutely the best service I high recomend anyone thinking about solar to use calidus 100% I can't recommend them highly enough.

Excellent communication with speedy delivery quality product, asked for a change to black glands and Z brackets , done with no additional charge

Great service from Alex & the team sorted my system out for me & delivered in a couple of days great turn around & well packaged 👍

Great piece of kit, excellent value for money (purchased while on offer) great delivery even though we purchased between Christmas and New Year.
Being installed next week

What a solar panel quality product well made and the service I received was excellent highly recommend this company

The staff and the team are so helpful I had an issue with my solar panel and Tom Howe and his team sorted it out within hours. So grateful to them all. Regards Mike Collins
