FAQs
1. Which batteries are compatible with the SPH 10000TL-HU-US(B)?
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, so the inverter and battery exchange real-time data on charge rates and protection limits. For best integration, we recommend Growatt ALP 48V batteries — but the dual battery ports and open communication protocol give you room to design or upgrade your storage flexibly.
2. Can I use the SPH 10000TL-HU-US(B) without batteries?
Yes. The inverter can power your home directly from solar during the day in grid-tied mode without any batteries connected. Keep in mind that without a battery, the system will shut down during a grid outage for safety reasons (anti-islanding). If backup power matters to you, we recommend starting with at least one 48V battery module — you can add more capacity later at any time.
3. How many SPH units can be connected in parallel?
Up to 6 units can operate in parallel, expanding total output from 10kW to as much as 60kW of combined inverter capacity. This makes the SPH 10000TL-HU-US(B) suitable for growing households and light commercial installations — start with one unit today and scale without replacing your core equipment.
4. How fast does it switch to battery power during an outage?
In Backup/UPS mode, the transfer time is under 10 milliseconds — faster than a desktop computer can register an interruption. Lights stay on, computers don't reboot, and most electronics never notice the switch. Combined with 120/240V split-phase output, it covers your whole panel including 240V loads like well pumps, HVAC, and electric ranges.
5. Does the inverter support a backup generator?
Yes. The SPH 10000TL-HU-US(B) features dual AC inputs — one for the utility grid and one dedicated to a generator. This is a key advantage for outage-prone areas: when a storm drains your battery bank over multiple days, the generator input lets you recharge without waiting for sunshine, with the inverter managing the charge process automatically.
6. Is the SPH 10000TL-HU-US(B) certified for US grid-tied installation?
Yes. It is certified to UL 1741 (SA/SB) and IEEE 1547 — the standards US utilities require for grid-interactive inverters. This certification covers interconnection approval in most US jurisdictions, though local permitting requirements vary by county and utility. Always confirm requirements with your installer and local authority having jurisdiction (AHJ) before installation.
7. The unit weighs 42.5kg (93.7 lbs). Is installation difficult?
The weight reflects industrial-grade components and a robust transformer design — it's a two-person installation, and the included wall-mount bracket simplifies positioning. Most installations are completed by a licensed electrician in a single day. We provide detailed installation manuals, wiring diagrams, and free technical support (email and WhatsApp) through the whole process.
8. What does the 10-year warranty cover, and how do I register?
The SPH 10000TL-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 your product after purchase through our support team (support.pps@growatt.com) with your order number and installation details. Keep your proof of purchase — registration takes under five minutes and activates full warranty service.
9. Should I choose the 8kW or the 10kW model?
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?
