With reference to the Victron 'NMEA 2000 & MFD integration guide' - Page 2 'Limitations' (extract below) last line indicates that a BMV always needed in a Marine installation.
@Guy Stewart (Victron Energy Staff)
Guy or anyone else. Can you advise why this is required. I have a Lynx Shunt 1000 with VE.Bus BMS and VenusGX etc.
Thanks.
Hi @Michael Riley, not to worry, you’re fine with that Lynx. No need for a BMV.
I’ll rethink that text, and probably remove that bulletpoint; its trying to explain something too complicated and not relevant.
@mvader (Victron Energy Staff) The CCGX documentation says that a BMV is needed for marine use on page 18.
=================
(D) Other system types
When there are more chargers, or loads, connected to the battery than just the Multi or MPPT Solar Chargers, a dedicated Battery Monitor will be required. Examples are:
House loads in Marine or Vehicle system.
PWM Solar Chargers
AC chargers, such as Skylla-is, Phoenix chargers, non Victron chargers, etc. Alternators
DC-DC chargers
Wind turbines
Hydro turbines
=============
I figured the Lynx ion shunt would track all in and out of the batteries. Can you confirm that a BMV is not needed if a lynx ion 1000 shunt is between the batteries and all loads?
Jon
Thanks For the confirmation.
I have 1 outstanding issue. Do you know if an MPPT 150/85 TR can get battery voltage from a CCGX or do I need to add a battery sense?
Ccgx itself doesnt measure the battery voltage. But, if you have a battery monitor connected (lynx ion) then yes, it can get the data from there and give it to the mppt as voltage sense
Acknowledged. Thanks.
