Forced-charging (when it's useful)

If winter clouds or short days leave your battery half-empty, forced-charging during a low-rate window can restore your evening coverage. The idea is simple: buy cheap, avoid buying dear.

Practical tips

Keep minimum state of charge high enough for backup (if that matters to you).
Limit forced-charge to avoidable imports (don't over-fill if you won't use it).
Re-evaluate after season changes—you might not need it in summer.

Talk to your installer about automations in your inverter app and any VPP constraints (some programs define when and how you can charge/discharge).
