• Is there much need for Current Sensing with LiFEPO4 profiles?

  Pb batts need adsord LiFe does not and can be largely sensed by the \"knee\" Therefore, is there significant value in tracking battery current? Solar is mostly voltage tracked. With a once a d...

• How to manage state of charge while on shore power

  I\'ve seen a system 3s, 4p, no bridging between strings, and it\'s in balance after 4 years. Good cells are amazing Only way to do SOC control I know is using switched outputs on BMV712 to trig...

• ABYC and REC

  As I read the ABYC requirements there seems to be a need for an Alarm before disconnect, and possibly seperate charge and load bus control. It already seems to meet the temperature and charge moni...

• Li Profile - Voltages

  Can I politely suggest the voltages on the lithium profiles in the WS App are too high? I can back with references if you like. 3.6 is a max, maybe once a day, with 3.5ish being safer. Depen...

• Canbus / NMEA2K / STNG

  I think they need to be seperate buses / terminations with gateway Some of the RM backbone devices block traffic if not powered. I\'m not sure which one\'s yet. Testing.

• Alternator Amps

  Will you update here when you see results? I\'m looking at similar WS500 / REC Q / Victron GX integration

• Alternator Amps

  If the shunt is on the battery, that is good for tracking charge state as current tapers with constant voltage, and perhaps terminating charge based on profile. Also good for keeping battery curre...

• Motor not running - reduce rotor current

  If motor is not running or tach is zero, reduce rotor current to 5% or similar. Just enough to sense if motor / tach starts. Removes chance of cooking rotor.
