Growatt SPH 10000TL-HU-US(B) 10kW 120/240V Hybrid Solar Inverter

The Growatt SPH 10000TL-HU-US(B) is a 10kW hybrid solar inverter with 120/240V split-phase output for residential solar, battery storage and backup power in Canada. It combines three MPPT trackers, a 48V-class battery connection and integrated transfer functionality to manage energy from solar panels, batteries, the utility grid and a compatible generator.

Why choose the Growatt SPH 10kW hybrid inverter?

• 10,000W rated output: Supports 120/240V split-phase systems, with 120/208V operation also listed in the datasheet for supported configurations.
• Three independent MPPTs: A maximum recommended 15,000W solar array provides a 1.5 DC/AC ratio for flexible PV system design.
• 48V-class battery storage: Supports compatible lithium or lead-acid batteries within a 40-60V operating range, with CAN/RS485 communication.
• Up to 200A battery charging and discharging: Supports up to 10,000W of continuous battery charge/discharge power when battery voltage, capacity and current limits permit.
• Fast backup transfer: Integrated UPS functionality provides a transfer time below 10ms in the supported backup configuration.
• Flexible system integration: Supports DC-coupled solar, AC-coupled and AC-retrofit applications, plus generator charging.
• Built-in protection: AFCI, anti-islanding, ground-fault monitoring and Type II surge protection on both AC and DC sides. The (B) version includes integrated circuit breakers.
• Expandable capacity: Supports up to six units in a compatible parallel installation.

SPH 10000TL-HU-US(B) technical specifications

Technical specifications and warranty are from Growatt's November 2024 SPH 10000TL-HU-US datasheet, including the (B) version. The inverter certification document explicitly includes SPH 10000TL-HU-US(B). UL 9540 coverage applies to the approved complete SPH(B) ALP ESS US configurations.

Solar, storage and backup for your home

Use the SPH 10kW hybrid inverter to combine solar generation with compatible battery storage and backup loads. The platform supports new DC-coupled PV systems and supported AC-coupled retrofit designs. Generator charging can provide another energy source when solar production is limited.

The 10kW output rating, available battery power and individual circuit requirements determine which loads can operate together. Have the battery bank and backup circuits sized for running loads and startup demand. Confirm the approved battery model and communication settings before ordering.

Frequently asked questions

Does the inverter have an integrated automatic transfer function?

Yes. The inverter provides integrated transfer functionality and a UPS transition below 10ms in its supported backup configuration. The (B) version also includes built-in breakers. The complete installation still needs the appropriate electrical protection, wiring and backup-load design.

Can I use a 48V lithium battery?

The inverter supports compatible 48V-class lithium batteries within its 40-60V operating range. Check the exact battery against Growatt's approved battery list and confirm BMS communication and current limits.

Is the inverter certified for Canadian installations?

The certification document includes this (B) model under CSA C22.2 No. 107.1 and CSA C22.3 No. 9, along with the listed UL and IEEE standards. Your installer should confirm the applicable utility interconnection requirements for the project.

What does UL 9540 cover?

The separate energy-storage certification covers listed SPH(B) ALP ESS US inverter-and-battery system configurations. Confirm the approved combination and battery capacity for your installation.

Can I connect a generator or add remote monitoring?

The datasheet supports generator charging with up to 10,000W generator input and WiFi monitoring accessories.
