Knox Krypton ECO-PV6600 6.2kW Hybrid Inverter

Note: 6200 W from up to 6600 W of PV on a 48 V battery bank, with a 90 to 450 V MPPT window and an 18,000 VA surge, more than double the Eco 5000. Float charge 54 V, overcharge cut-off 63 V. Knox model code 6.2kW-48-pV6600-TWIN. 10.4 kg in the same 300 × 435 × 115 mm case as the Eco 5000. The datasheet prints a "Rated Power" line (6600 VA / 6600 W) that is higher than anything it delivers: 5000 W from the battery alone and 6200 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. Price shown is Rs 102,000 at both w11stop.com and Kamal Solar (in stock), read 21 September 2026.
