I found Bimble Solar very helpful and accommodating.
Ordered a 30A MPPT Controller (Tracer), Bluetooth and Temperature Kit. It arrived the next day along with some sweets. They are a brilliant company. Well respected in the Camper and Motorhome communities. If you are looking for advice, they will generally reply to emails.
