Knox Krypton 5600 4kW Hybrid Inverter

Note: The only 24 V model in the Krypton range: 4000 W output from up to 5600 W of PV on one MPPT, with a 60 to 450 V window on a 500 V ceiling and 27 A input current (40 A maximum), starting at 120 V and feeding the grid from 150 V. 120 A from solar and from mains. Surge 8000 VA, 18 A nominal output current. Float charge 27 V, overcharge cut-off 33 V. Parallels to 9 units in the table, although the front page says 6. The datasheet prints its grid output range as 170 to 280 V, the same figures as the off-grid input windows, rather than a feed-in window, so ask the dealer what grid voltage it exports at. Knox name the base model as the Hybrid Infini V IV 4kW Twin. 12 kg in a 313.6 × 457.5 × 119 mm case. Knox's datasheet files the whole Krypton range under a Grid-Tie Operation section with grid feeding, so it is listed as a hybrid, but it names no grid certification (no IEC 62116 anti-islanding or IEC 61727), so confirm your distribution company will accept it for net metering before planning an export system. Pure sine wave output with a 10 ms transfer for computers and 20 ms for appliances, 93% battery-mode efficiency and 95% maximum DC to AC conversion. Dual outputs for smart load management, a 12 V DC output of up to 100 W for a DC fan, LED lights or a router, RGB status lights, built-in WiFi with an Android and iOS app, USB on-the-go, and a reserved BMS port (RS485, CAN or RS232). It runs without a battery and accepts mains or generator input, restarting on mains once it returns to 180 V. Replaceable fan and a 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 a single Pakistani retail listing, Rs 97,000 at w11stop.com (in stock), read 21 September 2026. A Daraz seller asks Rs 175,000, far above other dealers, so it is not used.
