Microgrid Systems

Jonsson Tech is expanding into microgrid power solutions, built on Victron Energy's proven inverter/charger and monitoring technology.

A microgrid links multiple independent power banks — each with its own Victron inverter/charger, battery, GX monitoring device, and charge source (solar, generator, or AC) — onto a single shared AC circuit. The result is a combined power system that's more resilient and more scalable than any single unit alone: if one power bank needs maintenance or goes offline, the rest keep the load running.

Why it matters:

• Scalability — Add power banks as demand grows instead of oversizing a single system upfront.
• Resilience — Each power bank operates independently, so a fault in one doesn't take down the whole system.
• Flexible charge sources — Combine solar, generator, and AC charging across different power banks in the same microgrid.
• Built on proven hardware — Compatible with Victron's MultiPlus, MultiPlus-II, and Quattro inverter/charger families, monitored through a Victron GX device.

Where microgrids fit:

Off-grid communities and remote sites, multi-unit RV or fleet operations, commercial and residential backup power, and agricultural or disaster-relief power. Microgrids are also a strong fit for critical, always-on applications — data centers that can't tolerate downtime, communication towers that need resilient power to stay connected, senior living and old age homes where backup power is a safety requirement, and military operations requiring dependable, distributed power in the field. Anywhere a single power system isn't enough, or reliability can't depend on one point of failure, a microgrid is worth considering.

Charging the battery banks:

In a Victron microgrid, each power bank needs its own independent DC charging source — the inverter/charger's built-in AC charger isn't used in this configuration, so every battery bank needs a source that charges it directly, whether from solar, a generator, or grid power.

We pair Victron microgrid power banks with Thunderstruck chargers as a compact, versatile direct-charging source. They accept anywhere from 120V to 240V AC input, deliver up to 3kW of charging power, and are small and quiet enough to install alongside the rest of the system — making them a strong option for charging 48V battery banks directly from a generator or grid connection where solar isn't available or isn't enough.

Proper installation matters: overcurrent protection is required on every circuit, and touch-safe connectors are strongly recommended given how microgrid-configured inverters behave differently from a standard setup.

We're actively building out our microgrid design and installation capability. If you're planning a project that needs a resilient, scalable power system — or a direct-charging solution like the Thunderstruck setup above — contact Craig or Ryan to talk through your setup.
