Frequently Asked Questions

How much solar can the T-REX-40KHP3G01 take?

52 kW is the maximum PV input power, spread over four MPPT trackers that take 36+36+36+36 A of PV input current. Tracking runs from 200 to 850 V after a 250 V start-up voltage, around a 600 V rated PV input, from a 150 V minimum DC input voltage up to a 1000 V maximum PV voltage, at 99.9% MPPT efficiency.

What does the T-REX-40KHP3G01 deliver on the AC side?

40 kW rated output power and 40 kVA of apparent power, rising to 44 kW of maximum AC output at 63.8 A of maximum output current, three-phase at 220-230 V on 3L+N+PE wiring. It runs at 50/60 Hz from a 184-264.5 V input range, holds total harmonic distortion under 3%, adjusts power factor from 0.8 leading to 0.8 lagging, surges to 1.5 times rated power for 10 s and peaks at 97.6% efficiency, with 97% European efficiency. Grid settings cover NTS, UNE217001, UNE217002, CEI 0-21, NRS 097-2-1, NC RFG (Poland), VDE 4105, G99 and EN 50549-1.

What battery does the T-REX-40KHP3G01 work with?

160-800 V is the battery voltage range, carried on two battery inputs for LFP batteries at 50+50 A of maximum charging current and 50+50 A of maximum discharging current, backing up 40 kW. BMS communication runs over RS485 and CAN, the unit itself is reached over RS232 and RS485, and an LCD touch screen plus a WiFi or GPRS monitoring module report the bank. Transfer to backup takes 10 ms.

Where can the T-REX-40KHP3G01 be installed?

IP65 is the enclosure rating, so the wall-mounted chassis works outdoors from -25 to 60 °C with derating above 50 °C, in 0-95% non-condensing humidity and up to 3000 m of altitude with derating above 2000 m, under smart cooling. It weighs 85.6 kg net and 102.3 kg gross and ships in a 1114 x 774 x 469 mm package. The non-isolated unit carries overvoltage category III, surge protection level II, ground fault current monitoring and certification to EN 62477-1, IEC 62109-1 and IEC 62109-2, and up to 12 units can be paralleled.
