Product Description

The Growatt SPH 10000TL‑HU‑US‑B is a 10kW split‑phase hybrid inverter designed for residential and light commercial energy storage systems. It supports DC‑coupled, AC‑coupled, and AC‑retrofit configurations, enabling flexible integration with new or existing solar installations. With a 10ms UPS‑level transfer time, the inverter provides near‑instantaneous backup power for critical loads during grid interruptions.

This model supports high‑power 48V lithium and lead‑acid battery banks with up to 200A charging and discharging current, allowing rapid battery recovery and extended backup duration. Three independent MPPT trackers improve solar harvesting across complex roof layouts, while generator compatibility enables coordinated charging from diesel or gas generators when needed.

Built‑in Wi‑Fi, Bluetooth, and optional 4G connectivity provide access to Growatt’s monitoring platform for remote updates and performance analytics.

Features

  • 10kW split‑phase output — supports 120/208V and 120/240V systems for residential and light commercial applications.

  • Flexible system design — compatible with DC‑coupled, AC‑coupled, and AC‑retrofit installations.

  • High‑current battery support — up to 200A charge/discharge for 48V lithium or lead‑acid battery banks.

  • UPS‑level backup — 10ms transfer time for sensitive electronics and critical loads.

  • Generator integration — supports diesel and gas generators with configurable charging priority.

  • Triple MPPT architecture — three independent trackers with two strings each for optimized solar harvesting.

  • Advanced protections — AFCI, Type II surge protection (AC/DC), over‑current, over‑voltage, ground fault monitoring, anti‑islanding, and insulation resistance monitoring.

  • All‑weather operation — NEMA 4 / IP65 enclosure with operating range from ‑13°F to 140°F (derating above 113°F).

  • Connected monitoring — Wi‑Fi, Bluetooth, and optional 4G for remote updates and system analytics.

  • 10‑year manufacturer warranty.
