While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more

Purchaed Kit 37 3KVa Full Victron kit

Purchaed Kit 37 3KVa Full Victron kit - Had to replace the solar with 2 x Victron 185w units to fit my Sprinter L1 conversion job. All worked at first switch . Instructions need some clarification for civilians regarding AC neutral into / out of isolator and fuse sizes not stipulated on some pages . Being an Electronics Engineer it was not an issue but a first time builder may generate support queries . Happy with customer service and would buy again .

Good solar panel

Order processing and delivery was faultless. The kit is very good, except for the ABS plastic mounts, which I replaced with Renogy z-angles. No instructions were provided with the kit, though it was easy enough to work out.

I called with a query and was assured of a same day call back, however, no phone call ever came.

I would probably advise buying what you want separately and not having plastic mounts it would probably be cheaper.

Their recommended kits are a joke

Their recommended kits are a joke. I filled out their quiz and it recommended me a 3kVA inverter/charger to power a 150W ebike charger. They have the option to include a single 220Ah AGM battery with a 3kVA inverter which is completely unsuitable.

Hi Nancy,
Our Quiz is there to guide our customers, and this will give you several options from a 500vA system right up to the 3000vA system, of course we offer all sorts of options to meet customers needs and budget when it comes to batteries, therefore some cheaper battery alternatives are offered but which are still more than suitable.
it is a shame you felt the need to leave us a review, before contacting one of our specialist team members.
if you would like to get in touch so we can help you out please email us and we will be more than happy to help

The team at Callidus were immensely helpful and supportive. I cannot recommend this company enough. I purchased a complete inverter and battery system, and they helped me set it up every step of the way, even into the late evening, well beyond the call of duty! Exemplary customer service. Thank you so much.
