Description
I am using DVCC - Distributed Voltage and Current Control with Victron GXCC and recently updated my firmware and the rate of charge is being limited to about 600 watts total.
I have three SmartSolar MPPT charge controllers and if I turn the power inputs on the other two off. The maximum charge follows the turned on controller.
Everybody who has listed their configuration has the battery capacity set at the default of 100AH.
What values should I put in for five modules in parallel for:
- Battery capacity
- Maximum pack discharge
- Maximum charge current
Thanks
My current notes on how I set it up:
//
// Firmware setup
//
- Connect with Termite
- You will be presented with a rolling display
- enter a S to enter setup mode
- select the battery menu with the "b" command
- issue the "f" command to return to factory settings
- use the "r" command to reset the AH counter
- set the number of cells in series with the command "a 6"
- set the number of modules wired in parallel with the command "0 5" for my five modules
- set the battery capacity with the command "7 1125"
- set the maximum pack discharge with the command "8 500"
- return to the main menu with the "q" command
- select the Current Sensor Calibration menu with the "c" command
- Select state of charge based on voltage with the "2 1" command
- return to the main menu with the "q" command
- select the contactor menu with the "k" command
- Change the PWM for the contactor to always be on with the command "3 255"
- return to the main menu with the "q" command
- select the charger menu with the "e" command
- set the pack maximum charge current with the command "3 240"
- Issue the "5" command with until it reads (Victron/SMA) or Relay Control
- Issue the "8" command until it reads: Charger HV Connection: Behind Contactors
- return to the main menu with the "q" command
- return to normal operating mode with the "q" command. Note it is at this step that changes are recorded to storage.
