Ungrid watches battery reserve, aggregate demand, and incoming weather—then separates the signals that call for preparation, action, or a longer-range plan.
Connect Victron VRM or EG4 Cloud. No card required for Free.
Four signals. Four different decisions.
Each feature starts with a confirmed reading or forecast signal, explains why it matters, and leaves every equipment decision under your control.
This is the warning stage: reserve crossed the level you chose, but options remain.
What Ungrid sees
A scheduled check found reserve below the configured warning threshold.
What that buys you
Time to reduce flexible loads or prepare backup power using confirmed system context.
Low battery alert
From: Ungrid Alerts <[email protected]>
Battery: 28% and declining since 2:00 PM.
Right now: Solar is producing 420 W while the site is using 2.1 kW.
Next move: Reduce discretionary loads or prepare the backup-power plan while there is still time to choose.
Critical battery escalation
From: Ungrid Alerts <[email protected]>
Condition: SOC crossed your 15% critical threshold.
Trend: Load remains above incoming solar and reserve is still falling.
Act now: Move to the backup-power plan and shed nonessential loads. This critical alert was allowed to bypass Quiet Hours.
A second threshold creates a true escalation path. It turns a worsening reserve problem into a distinct, unmistakable message instead of repeating the original warning.
Low threshold
Prepare and reduce load
Critical threshold
Escalate and act now
Pro adds Quiet Hours, with options to let Critical Battery and High Load alerts break through.
High Load is a separate system-level signal—not a battery warning and not an equipment diagnosis.
What Ungrid sees
A scheduled check found aggregate load above the configured system limit.
What that buys you
A reason to investigate unusual demand before it consumes more of the expected reserve.
Ungrid reports system-level aggregate demand. It does not identify which appliance, circuit, pump, or other equipment caused it.
High Load Alert
From: Ungrid Alerts <[email protected]>
Aggregate load: 2.1 kW at the latest confirmed system check.
System context: Solar is producing 420 W while battery reserve is 61%.
Investigate: Demand is above the limit configured for this system. Ungrid cannot identify which load caused it.
A forecast only says what may arrive. Ungrid combines the forecast with your reserve, recent energy use, and solar outlook to show what to consider before the clouds move in.
Storm Watch is forecast-aware reserve planning: energy guidance, not an official weather alert, and it never controls your equipment.

Solar outlook
Moderate
Today: Morning clouds should clear near noon. The strongest solar window is expected from 12:30–3:30 PM.
What changed: Overnight use was higher than the recent average, leaving less reserve than yesterday morning.
Plan: Delay flexible loads until the clearing window and reassess reserve before evening.
Clarity includes the gaps
Reserve Outlook distinguishes missing telemetry from missing weather. When the inputs are not ready, it shows the limitation instead of presenting a reserve projection as current.
Check your vendor connection for recent readings. If you need to act before fresh data arrives, use your equipment readings and your backup-power plan.

Control and safety
Ungrid reads supported energy telemetry and stores vendor credentials in Google Cloud Secret Manager. It never sends control commands through Victron or EG4. Any future controllable feature requires a separate, explicitly enabled compatible connection.

The planned Tesla Car Charging feature will let you set when the car must be ready and how much home reserve to protect, then coordinate compatible charging around stronger solar windows and changing battery margin.
One watch duty. Three operating worlds.
The same confirmed signals lead to different decisions at home, across a farm, or aboard a yacht.
