Alternator Port › Setpoints

User setpoints (layer 3 of the limits model): current, absorption/float/charged voltage, temperature, BMS capacity/tail/charged time, absorption max time, house current budget, RPM gate.

⚠️ Not yet verified on board.

How to get there

http://192.168.10.41/ → the numbers ending · Port (HA: Alternators › Port)

What it does

Change a number → new target for the charge controller, always clamped below the fixed hard limits (250 A / 14.4 V / 125 °C) which no UI can change. ⚠️ Safety-critical.

Before you start

Also: human on board

What you should see

Numbers show current values; a change takes effect within a control cycle and is kept across reboots.
