SolarMax SM-SOLON-3KW Hybrid Solar Inverter

The latest SolarMax SM-SOLON-3KW Hybrid Solar Inverter price in Pakistan is Rs. 65,000/- updated on August 30, 2026.

Overview:

The SolarMax SM-SOLON-3KW Hybrid Solar Inverter is a 3,000W single-phase off-grid/hybrid unit built around a 4KW-capacity MPPT solar charge controller, delivering up to 80A of charging current to a 24V lead-acid or lithium battery bank. It works with or without a battery connected, and the wide 60–450V DC MPPT input range gives installers real flexibility in how panels are strung across the array.

Pure sine wave output at 230VAC ±5% keeps sensitive electronics running cleanly, and the unit is rated for a 6,000VA surge — double its continuous rating — to ride through motor startup and other inrush loads without tripping. Charge and discharge protection covers overcharge and undervoltage conditions automatically, and built-in WiFi plus RS485 communication (BMS-compatible with lithium batteries) gives installers a path to remote monitoring or BMS integration without extra hardware.

This model doesn’t appear on SolarMax’s current official product lineup (which has since consolidated the SOLON series around the 6kW IP65 model), so it’s likely an earlier or lighter-duty generation still in circulation through Pakistani resellers. SolarMax’s own cached product page confirms a 2-Year Unlimited Parts Replacement Warranty with Lifetime Free Service Warranty on this model.
