The MAX Series Off Grid Solar Inverter is purpose-built for standalone solar power systems — combining MPPT solar charging, battery management, and pure sine wave AC output in one rugged unit.

1. What Is an Off Grid Solar Inverter?

Unlike grid-tied inverters, an off grid inverter operates in islanding mode: reads solar energy, charges batteries, and supplies stable AC power to loads — all without grid connection.

2. Core Features

• Built-in MPPT charger: 80–100A, 20–30% more efficient than PWM

• Pure sine wave output: THD <3%, safe for sensitive electronics

• Battery compatible: lead-acid, AGM, gel, LiFePO₄ — adjustable parameters

• Multi-source priority: solar first / generator first / battery first

• UPS function: <10ms transfer to battery on AC failure

3. Real-World Use Cases

Remote telecom base stations, rural home/village electrification, agricultural water pumping & cold storage, hospital/clinic backup power.

4. Sizing Rules

List all loads in Wh/day; size battery for 1–3 days autonomy; choose inverter ≥1.25× total connected load to handle motor surges.
