Growatt 10kW Hybrid Inverter | SPH 10000TL-HU-US

Most hybrid inverters ask you to choose: AC-coupled retrofit, DC-coupled new build, or AC-coupled battery addition. The Growatt SPH 10000TL-HU-US doesn't make you choose — it supports all three configurations in a single unit, which means your system design isn't locked in at the point of purchase.

The 10ms backup switching time is the spec that matters most in a power outage. Most hybrid inverters take 20–100ms to switch, which is long enough to reset computers and drop sensitive loads. The SPH switches in 10ms — fast enough that most equipment never notices the grid went down.

At 10kW continuous output with up to 15kW of PV input, the SPH 10000TL-HU-US is sized for mid-to-large homes with meaningful solar array capacity. It's UL listed, 120/240V split-phase, and monitors via the Growatt ShinePhone app. If you're designing a system and want to know whether this inverter fits your load profile, use our Build Your System guide before ordering.

Does this inverter work without batteries?
Yes — it can operate in grid-tied solar-only mode without a battery. The battery is required for backup power functionality.

What batteries are compatible?
The SPH 10000TL-HU-US supports high-voltage lithium batteries (such as Growatt's GBLI series) as well as standard 48V lithium packs. Confirm your battery's communication protocol with your installer before purchasing.

Can I add this inverter to an existing solar system?
Yes — the AC-retrofit and AC-coupled configurations are specifically designed for homeowners who already have solar panels and want to add battery backup without replacing their existing array.

Does it support generator input?
Yes, the SPH 10000TL-HU-US supports AC generator input for charging batteries when solar production is insufficient.
