Both run on 24V with identical 900W solar support and TwinCharge tech — the 3KVA's higher VA rating means it can sustain a larger combined appliance load simultaneously, useful once your essential circuit includes things like a water pump or multiple high-draw devices at once.
The 25V VOC rating defines the maximum open-circuit voltage your panel string can produce — most standard 12V-class panels stay within this comfortably, but if you're stacking panels in series, this is the number to check against before wiring.
16.6 kg — heavier construction reflecting the larger internal components needed to handle 3kVA continuously; factor this into your wall-mount planning.
Yes — pure sine wave output is built to handle high-starting-current loads like pumps and motors without instability, a common pain point with cheaper inverters that struggle with motor inrush current.
Short-circuit protection, reverse polarity fuse, and thermal safeguards work alongside the TwinCharge logic to prevent the overcharging risk that basic, non-intelligent PWM controllers can introduce on hot days.
