Lynx Smart BMS: Allow to charge “Yes” but ATC contact open

[pwfarnell]

1. A 0.5A fuse could allow a higher current for a short period.
2. Switching a contactor can result in voltage / current spikes if flyback diodes are not used. We often see people damaging the control relays on equipment by driving contactors / large relays.

Using inverter / MPPT / GX device programmable relays with higher current, inductive or capacitive loads

Many Victron products have programmable relays included which can be used to send signals between each other or to control small loads. These ae typically rated as for the Cerbo GX as DC up to 30 VDC: 6 A DC up to 70 VDC: 1 A AC: 125 VAC: 6 A There have been many reports within the community from people who have burnt out the contacts or welded the contacts closed in the programmable relays in their systems. This is often caused by connecting the relays to inappropriate loads, sometimes loa…
