System on sailing boat: 2 x 200AH LiPo, VenusGX, VE.Bus BMS, 2xBP220, Multi 24/5000,, MPPT150/70, Lynx Shunt 1000 +Pwr in and Distributor, Digital remote. Shore Power / Generator manually selected to Multi.
Question: How to wire the +ve for Venus and MPPT whilst:
a. maintaining all loads after BP220 (except BMS) and Multi (as per doco);
Have read manuals for VenusGX, BP220, VE.Bus BMS, etc. Noted the warnings about a 'hang up' in case of BP disconnect due to low cell voltage and am therefore looking for a reliable 'restart' after a BP220 disconnect for low cell voltage assuming that our 'recovery' method is to say, start the AC generator which will power the Multi (Charger) and thus the Battery voltage rises.
As I understand it from wiring i.a.w. documentation the BMS load disconnect is connected to the Terminal H of BP (0.6 mA x 2 draw). Venus (110 mA @ 24V) is powered from BMS (Load Disconnect of BMS max 2mA). Multi, MPPT and BP220(2) are all connected to Lynx Distributor (i.e. after the Lynx Shunt). From this I understand that ALL loads (except BMS) are able to be disconnected on 'alarm' (Hi, Low, temp). From GX manual I understand that the VE.Bus BMS will wait for the Venus to power up and with above (Venus powered from Load disconnect of BMS - as per documentation) when will the Venus get power? Suggestion with power sequencing explanation please.
After the above, add in where the MPPT should be powered. Before the BP220 and I now have an uncontrolled load on the LiPo (i.e. it is night and not charging). After the BP220 and solar energy will not charge the LiPo until the Venus is back on line.
