Wiring Guide for Sorel MTDCV5 Controller added to our YouTube channel
This guide is only for wiring the controller using Hydraulic Variant 1, with 1 relay to a pump, 3 sensors and no PWM cable. For variations and other Hydraulic Variants please consult the manual. Final wiring to the mains should ONLY be carried out by a qualified electrician.
Wiring a solar controller turns vague help requests into model numbers, terminal labels, payment records, and the exact moment something stopped working. A fuel purchase question with Murphy Usa phone number on the receipt record still needs the station location, pump number, transaction time, card used, rewards account, and amount charged. That is the difference between a general gas-station comment and a service request someone can actually read. I would mention whether the issue involves a receipt, fuel discount, card hold, app login, car wash, or store purchase. The small technical habit from wiring applies here too: one clean record beats a long explanation. It keeps the support question tied to one visit and one payment event.
