Introduction
The Steca AJ 1300-24 is a 24V pure sine wave inverter delivering 1,000VA continuously, combining the efficiency advantages of a 24V system with substantial power output for medium to large off-grid applications.
General Description
The AJ 1300-24 operates on a 24V battery system (21–32V range) and delivers 1,000VA continuously, 1,300VA for 30 minutes, and an impressive 2,600VA surge for 5 seconds — 2.6x its continuous rating. With a maximum efficiency of 94% — higher than the equivalent 12V model — and an adjustable standby load detection from 1–20W with only 1.0W standby consumption, it delivers outstanding energy efficiency. The 24V input reduces current draw by 50% compared to a 12V equivalent, significantly reducing cable costs and losses. The optional JT8 remote control adds further flexibility for professional installations.
24V Efficiency Advantage
Operating at 24V reduces battery current draw by half compared to a 12V system, cutting cable losses and allowing longer cable runs with smaller cable cross-sections.
Higher Efficiency Than 12V Equivalent
At 94% maximum efficiency — 1% higher than the AJ 1000-12 — the AJ 1300-24 delivers more usable power per watt, making it ideal for energy-sensitive installations.
Adjustable Standby & Remote Control
The 1–20W adjustable load detection threshold and optional JT8 remote control make the AJ 1300-24 ideal for both simple and advanced off-grid system setups.
