Knox Krypton ECO-PV5000 4.2kW Hybrid Inverter

Note: 4200 W from up to 5000 W of PV on a 24 V battery bank, with a 30 to 450 V MPPT window and an 8400 VA surge. Float charge 27 V, overcharge cut-off 32 V. Knox model code 4kW-24-pV5000-TWIN. 9 kg in a 300 × 435 × 115 mm case. The datasheet prints a "Rated Power" line (5000 VA / 5000 W) that is higher than anything it delivers: 4000 W from the battery alone and 4200 W with solar and battery together, which is the figure in the model code, on the front page and in the title here. Knox list feed-into-grid and grid feeding as features, but this datasheet has no grid-output section and names no certification at all, so confirm net-metering approval with the dealer before planning an export system. Single MPPT with a 500 V ceiling, 18 A rated PV current (20 A short circuit), and 100 A solar charging with 120 A from mains. AC input selectable at 184 to 264 V or 195.5 to 253 V. Pure sine wave, 230 V ±5% in battery mode, 93% peak efficiency, 10 ms transfer for computers and 20 ms for appliances. Dual output, battery equalization for lead-acid banks and a reserved BMS port. Communication is RS232 with WiFi as an option. Built-in anti-dust kit. Rated -10 to +50 °C. The datasheet gives no IP rating and no warranty term, so ask the dealer for both.
