Crown Yorker 5kW Off-Grid Inverter

Note: 5000 VA at power factor 1 on a 48 V battery bank (42 to 56.4 V) from up to 6000 W of PV, over a 120 to 430 V MPPT window with a 500 V ceiling and a best-tracking band of 300 to 340 V. 18 A of PV input current, 80 A of battery charging, 40 A of AC input and 15.6 A out at 220 to 230 V. Parallels up to six units on a built-in parallel kit, which is the reason to choose it over a single larger inverter. Overcurrent protection trips at 10 s for 110 to 130% load and 0.2 s above 150%. MPPT tracking efficiency is quoted at 99.5%, but no PV-to-AC conversion figure is published, so the efficiency field is left empty rather than filled with a number that measures something else. Crown label it an off-grid hybrid, and nothing in the sheet documents grid export. RS232 at 2400 baud, a lithium BMS communication card and a dry contact. The operating temperature row is wrong on the datasheet: it reads -10 to +15 degC and then says output derates above +50 degC, which cannot both be true, so it is not recorded here. Dimensions and weight are not published either. Price shown is the w11stop.com listing, Rs 106,000 (in stock), read 26 September 2026; its MPPT window, 80 A charging and 220 to 230 V output all match this datasheet.
