Solution

Off-Grid Energy Storage

Complete power independence for remote homes, lodges, mines and islands.

The Challenge

Remote sites face a stark choice: a costly grid extension, a fuel-hungry generator running 24/7, or a properly engineered off-grid solar system. Undersized systems fail in the first cloudy week; oversized ones waste budget.

The PATTERN Solution

PATTERN engineers off-grid systems from the load profile up: PV array sized for the worst month, LiFePO4 storage for 2–3 days of autonomy, and a hybrid inverter that manages generator backup automatically.

Rack-mounted and floor-standing batteries scale systems from 5kWh cabins to 100kWh+ lodges and mining camps.

System Structure

  1. 1 PV array with MPPT charging
  2. 2 Hybrid inverter as the system hub
  3. 3 LiFePO4 bank with 2–3 days autonomy
  4. 4 Automatic generator start on low battery
  5. 5 Remote monitoring for unmanned sites

Capacity Selection Guide

  • Cabin / tiny home: 5kW + 10kWh
  • Family home: 8–10kW + 20–30kWh
  • Lodge / mining camp: parallel inverters + 100kWh+

FAQ

Off-Grid Energy Storage — FAQ

How many days of autonomy should I design for?

Two to three days covers most climates; tropical rainy seasons may need more. We size from local irradiation data.

Can the system call a generator automatically?

Yes — the hybrid inverter starts the generator at a set SOC and stops it when batteries recover.
