Find the right monitoring setup for your build. Monitoring is brand and product specific — we match recommendations to your ecosystem, budget, and use case.
Size your system first — then pick your monitoring
Monitoring recommendations are most useful once you know your component ecosystem (Victron, Renogy, etc.). Run the 60-second wizard to size your system, then come back here.
Your Component Ecosystem
Monitoring is tightly coupled to your component brands. Select the brand that dominates your build — inverter, MPPT, and battery.

Monitoring principles
Monitoring is advisory — it doesn't affect component selection. Pick your components first, then choose how to monitor them.
State of charge (SOC) is the most important metric. A shunt-based monitor is far more accurate than voltage-based SOC.
Victron products share the VE.Direct/VE.Bus ecosystem — mixing Victron components gives you free Cerbo GX integration.
Cloud monitoring needs internet. For remote areas, local hub monitoring (Cerbo GX) works offline — VRM syncs when you get signal.
