SPE 15KTL3 HVM Hybrid Inverter

Product Overview

The SPE 15KTL3 HVM is a single-phase high-voltage hybrid inverter rated at 15 kW output. It uses 2 MPPT inputs with 1 string per MPPT at 25 A maximum current, accepting up to 18 kW PV input at a maximum voltage of 1000 V. The MPPT operating range is 200-850 V with a rated input voltage of 600 V.

The battery port accepts lithium and lead-acid batteries at 48 V nominal (40-60 V range) with up to 300 A charge and discharge current over RS485/CAN. The dual AC input supports both grid and generator sources with an integrated transfer switch. The dual AC output enables smart load management. Peak-shaving and valley-filling grid-tied functionality, 6-unit parallel operation and WiFi/4G monitoring complete the feature set.
