Growatt SPE 10000ES – Hybrid Inverter off-grid 10 kW

Growatt SPE 10000ES – Hybrid Inverter off-grid 10 kW

Growatt The SPE 10000ES is a single-phase hybrid inverter with a rated power of 10,000 W, combining two independent trackers in one housing MPPT, a pure sine wave inverter, and a backup power module. It operates from a 48V lithium or lead-acid battery and supports off-grid installations, standby power, and rooftop self-consumption. Switching to backup power takes less than 20 milliseconds, which is faster than it takes a computer or circulating pump to detect a power outage.

The most important features

• Two independent trackers MPPT, one chain per tracker
• Maximum recommended panel power 12,500 W with a rated AC power of 10,000 W

• Operation with a 48 V battery, charging current up to 220 A and discharging current up to 240 A
• 10,000 W emergency power supply with a transfer time of less than 20 ms
• Parallel operation of several units for larger installations
• WiFi or 4G communication via module Growatt

Growatt SPE 10000ES - What to Look Out For

A hybrid inverter differs from a standard grid-connected inverter in that, in addition to the panels, it also supports a battery and can maintain power during a power outage. In this model, a separate emergency power module with a switching circuit is responsible for this. Upon detecting a power outage, the dedicated circuit switches to battery operation in under 20 ms. This is fast enough for computer equipment, boiler controllers, and circulation pumps.

Two independent trackers MPPT They allow the installation to be split between two roof areas with different orientations or shading. Each tracker maintains its own operating point, so a less-well-positioned string doesn't drag down the better one. The MPP voltage range from 60 to 480 V with a maximum input voltage of 550 V allows for considerable flexibility in selecting string length for typical modules.

When selecting panel power, it's worth utilizing the DC side of the grid: the manufacturer allows up to 12,500 W of panels with a nominal AC power of 10,000 W. This oversizing is beneficial in Polish conditions, as the modules only achieve their rated power in a narrow window of conditions, operating below it for most of the year. The surplus during peak summer days is reduced, but the profit for the rest of the season clearly exceeds this.

The battery operates at 48V, making it a low-voltage system—easier to service than high-voltage systems. Charging currents of up to 220A and discharging currents of up to 240A allow for operation with capacities of several kilowatt-hours without reducing output power. The device supports both lithium and lead-acid batteries, which is important when upgrading an existing off-grid system.
