I’m trying to work through setup to get DVCC to work with the WS500 Pro regulator.
Here’s my setup:
SOK 314 Ah batteries (2x, wired in parallel), connected to Cerbo GX via CAN-BMS. BMS provides max charge volts and current.
DVCC enabled (works with MPTT and Inverter/charger).
WS500 connected to CerboGX via VE.CAN.
Ws500 shows up on the Cerbo Gx as an alternator, but it only works in standalone mode.
DVCC enabled on the WS500, CANBUS set to 250 kbps, Alternator shunt enabled…
Anyone have gone through a similar setup and were able to get the WS500 to work as a slave and respect the DVCC limits?
As per the Wakespeed manual, have these dependencies been met?
With Wakespeed Firmware 2.5.2 and higher, the WS500 offers support to follow Victron Energy’s DVCC
(Distributed Voltage and Current Control) method. By default, the WS500 will follow the DVCC direction
issued to it via the Cerbo. Users are able to disable this function by toggling ‘Support Victron DVCC’ in the
Wakespeed App with Expert Mode enabled.
Dependencies for allowing DVCC to be utilized include:
• Cerbo firmware must be v3.30.
• Wakespeed firmware must be v2.5.2 or higher.
• Current Shunt must be located at the alternator.
• WS500 must be configured with “Shunt at Alternator” toggled on (Wakespeed application: System tab on the Configuration screen.)
• Define the Alternator Capacity in Amps on the Alternator Tab.
• NMEA2000 Support (System > Expert Mode) must be enabled.
The defined Alternator Capacity will be transmitted to the Cerbo as the capability to use for its calculations. If
no value is set, 200A is used by default.
There were WS500 Pro errors in Wakespeed firmware V2.6.0, you need 2.6.1.
However, I have a feeling that if you have batteries on BMS-CAN and the WS500 on VE-CAN you may not get full functionality as the 2 CAN systems are independent. I am not 100% definitely sure on this. Can you get your batteries to work at 250kbps so you can connect everything daisy chained on the VE CAN. There have been other posts like this, search for WS500 and DVCC.
I have venus os 3.72 (cerbo gx)
Wakespeed firmware is the latest 2.6.1 ??
Current shunt on the alternator
WS500 config with shunt at alternator toggled ON
Alternator capacity set as 175 A
N2K is enabled
The SOK batteries send all the usual commands (voltage limit CVL, charge current limit, CCL discharge current limit DCL), temps, the high/low cell voltages, and all the warnings/errors expected…
The connection does say can-bus
I find it strange that DVCC picks all this up and sends it to other systems (MPPT, Inverter/Charger, etc…) but can’t send it to the integrated alternator? This is a huge disapointment thus far, as both the Victron and WS 500 side said they were Victron / DVCC compatible (but nowhere did it say you have to use Victron batteries with Victron Lynx…).
The batteries alternatively can be configured for NMEA 2000 output … since all the N2K data passes through the WS500 and ends up on the CerboGX via VE.CAN, I’m curious if I connect the SOK battery to the N2K network if the CerboGX will recognize it as the controlling BMS if connected that way instead of CAN-BMS?
