Growatt SPH 8000TL-HU-US(B)
8kW Split-Phase Hybrid Solar Inverter

The inverter works with all standard 48V battery types, including LiFePO4 (lithium iron phosphate) and lead-acid batteries (AGM/sealed, gel, and flooded). It communicates with compatible lithium batteries through CAN or RS485 closed-loop communication, exchanging real-time data on charge rates and protection limits. With up to 190A of continuous charge/discharge current at 8,000W, it drives battery banks hard and fast. Growatt ALP 48V batteries integrate best, but the dual battery ports and open protocol keep your system design flexible for future upgrades.

Yes. The inverter powers your home directly from solar during the day in grid-tied mode, no batteries required. Without a battery, the system shuts down during a grid outage for safety (anti-islanding), so if backup power is on your list, start with at least one 48V battery module — you can expand capacity whenever your budget or loads grow.

Up to 6 units operate in parallel, expanding total output from 8kW to 48kW of combined inverter capacity — enough headroom for a growing household, a small multi-unit property, or a light commercial site. Start with one unit today and scale without replacing your core equipment.

In Backup/UPS mode, the transfer time is under 10 milliseconds — faster than a computer can register an interruption. The 8kW output at 40A covers a full split-phase panel including 240V loads like well pumps, mini-splits, and electric ranges, and it tolerates 1.5× rated power surges for 5 seconds to handle motor startups.

Yes. Dual AC inputs — one for the utility grid, one dedicated to a generator, with up to 8,000W of generator input on this model. When a multi-day storm drains your battery bank, the generator recharges it automatically without waiting for sunshine. The SPH also supports DC-coupled, AC-coupled, and AC-retrofit configurations, so it pairs with existing solar systems too.

Yes. It is certified to UL 1741 (SA/SB) and IEEE 1547 — the standards US utilities require for grid-interactive inverters — covering interconnection approval in most US jurisdictions. Local permitting requirements vary by county and utility, so confirm with your installer and local authority having jurisdiction (AHJ) before installation.

At 42.5kg (93.7 lbs) it's a two-person lift, and the included wall-mount bracket simplifies positioning. Dimensions are 457 × 874 × 256 mm, and the IP65 enclosure is rated for outdoor installation from -25°C to +60°C. Most installations are completed by a licensed electrician in a single day, supported by detailed manuals, wiring diagrams, and free technical support via email and WhatsApp.

The SPH 8000TL-HU-US(B) carries a 10-year product warranty covering manufacturing defects and component failures under normal operation, backed by Growatt's official after-sales service in the United States. Register after purchase through our support team (support.pps@growatt.com) with your order number and installation details — it takes under five minutes and activates full warranty service.

Start with your peak simultaneous load: add up everything that could run at once during an outage — fridge, well pump, HVAC, lights, electronics. If that total stays under 8,000W, the SPH 8000TL covers it and frees budget for more battery capacity. If you run central AC, an electric range, or EV charging alongside backup loads, step up to the 10kW model. Both accept the same 15,000W of solar and the same 48V batteries, so your array design doesn't change either way. Or check our guide 8kW vs 10kW Hybrid Inverter: Which Size Do You Actually Need?

Up to 15,000W of recommended PV power — a DC/AC ratio of 1.875 — across three MPPT trackers with two strings each (150–450V MPPT range, 525V max DC, 22A input per tracker). That deliberately oversized ratio lets you harvest more energy on clear days and recharge batteries faster, while the 8kW AC output keeps the inverter cost down. It's the same solar platform as the 10kW model, so upgrading later doesn't require redesigning your roof.
