Hybrid Inverter

Compared to conventional inverters, hybrid inverters offer the ability to not only feed the generated solar power into the utility grid but also store it in batteries. This allows the stored solar power to be used even when the sun isn’t shining. Another feature of hybrid inverters is their ability to optimize a household’s electricity consumption by prioritizing the direct use of generated solar power within the household before feeding it into the grid. This leads to lower energy costs and reduced dependence on expensive grid electricity.

Operating Modes – Configurable Depending on System Requirements

Online Mode

Various operating modes can be set to ensure optimal system integration of the SPH inverter. When configured directly on the device, a priority mode can only be set for a single time period. When using the online platform, up to three time periods can be set for the priority mode (a paid accessory is required to use this feature).

• Load first:In the standard “Load first” mode, the connected loads (consumers) are supplied with power first. As soon as the PV energy is sufficient for the load, the excess energy is fed into the battery. If the battery is fully charged or none is connected, the remaining energy is fed into the grid.
• Battery first:In this mode, the inverter first fully charges the battery using the maximum possible solar power. If the PV power is insufficient, the grid charging function can also be activated.
• Grid first:In this mode, the generated PV energy is first fed into the grid. Here, you can set the mode’s on and off times, as well as the power rate.

Backup Mode:

If no grid voltage is present at the device—for example, due to a brief power outage or blackout—the Growatt SPH automatically switches to backup mode. This ensures power is supplied to the AC output via the EPS-LOAD connection. The required power is supplied solely by the solar system and the battery. If the PV system also fails, the battery maintains the AC supply until it is fully discharged. If desired, the automatic switch to this mode can also be disabled.

Maximum Power Point Tracking

The use of Maximum Power Point Tracking (MPPT) technology ensures optimal energy yield in a solar system. The MIC inverter features an MPPT that adjusts the ideal ratio between voltage and current throughout the day based on solar irradiance and the temperature of the solar modules. Thanks to the wide MPPT voltage range, many solar modules can be connected, enabling efficient energy generation. This advantage becomes particularly evident when the sky is partly cloudy and light intensity is constantly changing.

Intelligent Load Management

The inverter’s integrated smart load control enables efficient and precise management of energy consumption. The dry contact allows electrical loads to be intelligently controlled and prioritized. This feature automatically detects energy demand and makes optimal use of available energy. Smart load management ensures optimal energy distribution, thereby contributing to efficient utilization. With intelligent load control via the dry contact, the inverter is able to optimize the flow of energy and ensure efficient operation of your solar system.

Growatt Monitoring Platform

The Growatt Monitoring Platform can be used with the optional Shine Series accessories. It is available as a smartphone app (for iOS and Android) as well as a web version. The Shine accessories must be purchased separately; use of the platform is free of charge. Through Shine, you can configure and monitor all your Growatt products; it also allows you to view your self-consumption and trends.

The following Shine options are compatible with the SPH series:

• ShineWiFi-X
• ShineLink-X
• Shine4G-X
• ShineMaster

Note on Using Growatt Inverters with Batteries

Please note that inverters from the MIN, MOD, SPH, and SPA series may only be operated with genuine Growatt batteries. All Growatt inverters sold in Europe are not compatible with lead-acid batteries. Using them may result in malfunctions or damage to the devices. Furthermore, no warranty claims can be made.
