Load study & sizing
We measure or model what the site actually draws — including the starting surge of the biggest motor, which sizes the inverter far more often than the average load does.
How we build
Mass Energy Storage System X · Built on Victron
Power that performs. Storage engineered on Victron.
MESSX designs, builds, and manages commercial and industrial energy storage systems around Victron Energy hardware — bidirectional MultiPlus-II and Quattro inverter/chargers, Dynamic ESS, SmartSolar MPPT, and VRM remote management. Proven components. Modular by design. Monitored from anywhere.

What we do
Mini-grids, built end to end
Generation, storage, conversion, distribution and control as one coordinated system — engineered to your loads, manufactured in our Seattle shop, and commissioned on your site by the same people who drew it.
Manufactured in our shop
Enclosure, busbars, distribution and every Victron component mounted, terminated and bench-tested under load before it ships — because faults found on the bench cost hours, not a return trip.
See the buildInstalled & commissioned
Placement, interconnection, earthing and a documented commissioning run with the numbers recorded — then as-built drawings, a labelled panel and a plain-language runbook.
What handover looks likeEvery source on one bus
Solar, generator and grid — where there is one — all land on the same DC bus through SmartSolar MPPT controllers and the inverter/charger, so the system uses whichever is cheapest and cleanest at that moment.
The componentsStorage that carries the night
A managed LiFePO₄ bank behind MultiPlus-II or Quattro inverter/chargers, sized to hold the site through the dark hours and transfer between sources without dropping the load.
Inverters & banksWatched and tuned remotely
Every system ships connected to the VRM portal — live data, alarms and reporting from any device, with remote firmware updates and dispatch tuning handled by us rather than by a site visit.
Cerbo GX & VRM
The platform
Built on Victron Energy
We don't lock you into a black box. MESSX engineers systems from Victron's modular, field-proven hardware — the same components trusted in demanding off-grid, marine, and industrial installations worldwide. Open, serviceable, and built to last.
MultiPlus-II & Quattro
Bidirectional inverter/chargers with PowerAssist and a built-in transfer switch. Stack them in parallel and across three phases as your load grows.
Dynamic ESS
Intelligent energy management that blends grid, battery, and solar around your tariff, forecast load, and solar yield — always drawing the cheapest available energy.
SmartSolar MPPT
High-efficiency maximum-power-point tracking gets the most out of your PV array — from compact units to multi-tracker MPPT RS controllers for large 48V banks.
Cerbo GX + VRM Portal
The system's brain and dashboard. Monitor and control everything through the free VRM portal, the GX Touch display, or the VictronConnect app — from anywhere.
Lynx distribution & BMS
Modular DC busbars, fusing, and the Lynx Smart BMS keep the battery bank safe, balanced, and simple to service and expand.
Lithium battery banks
Scalable LiFePO4 storage sized to your runtime and cycle needs, integrated and managed for a long, predictable service life.

Why it pays
Demand charges can be 30–70% of your bill. The system takes them on.
Utilities bill commercial sites for their single highest spike of demand each month — not just the energy used. With Dynamic ESS managing the MultiPlus-II bank, the battery absorbs those peaks automatically, so you stop paying premium rates for a few brief moments of load.
- Caps demand and shifts load away from peak tariffs
- Captures federal tax credits and accelerated depreciation
- Hedges against rising rates and demand-charge increases
- Every kWh tracked and reported in the VRM portal
How it works
