Engineered to outperform. Priced to dominate. Monitored like nothing else on the market.
Real-time telemetry, cell-level diagnostics, and predictive analytics that Sol-Ark's own platform simply can't match. Built by the engineers who build the batteries — not a third-party bolt-on.
Live inverter and battery data streaming via MQTT — voltage, current, power, SOC, temperature, and frequency across all phases. Sub-second visibility into your entire system.
Individual cell voltage monitoring across every string. Mismatch detection with automatic threshold alerts — info, verify, and service-call tiers. No other monitor does this.
Full L1/L2/L3 visibility for Sol-Ark 30K and 60K three-phase installations. Grid power, inverter output, PV production, and load distribution — per phase, in real time.
MQTT command authority to remotely disconnect batteries, disable grid charge, limit sell power, and override timer modes. Instant response. No truck roll needed.
Proactive notifications when your system needs attention — temperature warnings, SOC drops, grid outages, BMS faults. We call you before you even know there's a problem.
Every telemetry datapoint stored for the full warranty life of your system. 12+ million rows and counting. Complete history for warranty claims, performance analysis, and system optimization.
Not a mockup. This is an interactive simulation of the actual SunFusion Monitor dashboard — the same interface our customers and installers use every day. Watch the data stream in real time.
Your entire energy system — live on your phone. Real-time power flow, cell-level battery health, 3-phase monitoring, SMS alerts, and remote emergency control. No other solar monitoring platform comes close.
PWA App — Works on Any Device · No App Store Required · Instant Access
Solar production, battery state, grid import/export, and home load — all updating live via MQTT streaming. Not cached. Not delayed. Live.
Every individual cell voltage displayed in a real-time grid. Mismatch detection with automatic tiered alerts — informational, verification required, or immediate service call. No other monitoring system shows you this.
Battery temperature, inverter temperature, charge/discharge rates, and overall system status — all in one view. Know your system is healthy without opening a single panel.
Sol-Ark 30K and 60K three-phase installations get dedicated L1/L2/L3 power bars — grid voltage, inverter output, and load per phase. See imbalances instantly.
The monitor watches every cell in real time. When a single cell drifts even 20mV out of range, you see it highlighted immediately. Three alert tiers — informational, verify, and service call — so you act before failure, not after.
ECHO 4.0 through 6.0 HV packs run 3 to 9 strings. The monitor tracks each string individually — SOC, voltage spread, temperature delta, and charge balance across the entire pack.
Grid outages, battery events, temperature warnings, BMS faults — you get a text message the moment something happens. Not an email buried in your inbox. An SMS to your phone.
Disable grid charging, limit discharge current, kill sell power, or trigger a full emergency disconnect — all from your phone via secure MQTT. No truck roll. No waiting. Instant response.
Contractors and installers see every customer system in one place. Manage residential, commercial, and multi-inverter sites from a single login. Built for professionals managing real fleets — not a consumer toy.
