Hi, we are developing solution for complex energy storage remote control and monitoring. The system comprises of solar panels, energy storage (LiFePo batteries) and MultiPlus II inverters/chargers. Our device that controls the process comunicates with MultiPlus II units via Victron VE.Bus to NMEA2000 interface. We went through all specs available on victron web and through standard NMEA specs. However, there are still some things that we do not know:
-PGN 127501 (0x1F20D) - binary status report - we have no idea what is in these messages. We think they might contain device status (ie charging/standby, discharging, ...) however there is no specification for these messages. Does someone know how to decode these?
-PGN 127509 (0x1F215) and 127507(0x1F213) - victron documens state that these messages contain inverter and charger status information. However, data we are getting from these messages do not reflect the state of the inverters - messages tell us that inverters are on standby irrespective of their actual state.
-we are receiving messages with PGNs 61183 (0xEEFF) and 61439 (0xEFFF) that are not specified in either Victron or NMEA documents. What do these mean?
Can someone please help us clarify these data?
P.S. - We already decoded many basic messages from our solution (e.g. we can see basic electric quantities of inverters) - this proves our code is working.
