Off-grid power that stays online — even when nobody’s there

Off-grid system architecture (what we design around)

A reliable off-grid system is a balance of generation, storage, conversion, and control. We design for real-world behaviour: night loads, surges, seasonal variation, and “bad weather streaks”.

⚡

Key idea: we’re not just sizing solar and batteries — we’re engineering the behaviour of the whole system.

What we map in the design session

• Loads & duty cycles: what runs, when, and for how long
• Peak demand & surges: pumps, motors, compressors, workshop tools
• Autonomy target: hours/days you want to run without sunshine
• Generator strategy: if/when it starts, and what it must cover
• Monitoring & alerts: remote visibility via 4G/5G or Starlink
• Future expansion: adding loads later without redoing everything

Autonomy & load planning

Most off-grid failures aren’t “hardware failures” — they’re planning failures. We design around the tricky bits: long cloudy streaks, unexpected loads, and high start-up surges.

Common planning traps we avoid

• Underestimating night-time loads (security, comms, refrigeration)
• Ignoring motor start surges (pumps, compressors, tools)
• Designing only for “average weather” instead of worst-week scenarios
• Oversizing solar but undersizing conversion (inverters/chargers)
• No early warning system — finding out when it’s already down

🧠

Rule of thumb: your system should be stable on a bad week, not just a good day.

Off-grid explained (design, uptime, monitoring)

A short overview of how serious off-grid systems are built — and why monitoring matters more than people expect.

Jousto EMS for off-grid — 4G/5G + Starlink monitoring

In off-grid environments, Jousto EMS isn’t primarily about savings — it’s about not finding out too late. EMS is often more important on sites not visited daily, where small drifts can become downtime.

✓

Designed for remote sites: Jousto EMS can operate over 4G/5G and Starlink where supported.

What we monitor (examples)

• Battery state of charge, health indicators and drift
• Solar yield vs expected (early warning for shading/faults)
• Generator runtime and start events (where installed)
• Connectivity status (4G/5G/Starlink)
• Critical thresholds + alerts (so you act before downtime)

🧠

Practical goal: get an alert when performance shifts — not when the site is already down.

✓

Note: Jousto EMS is currently included when you purchase an off-grid system from Jousto. We’re not offering EMS as a standalone product at this stage.
