Hybrid inverters with energy storage: greenmondi's smart solution for your home

The energy transition is progressing – and with it the development of modern solar technology. At greenmondi, we monitor the changes in the market for energy storage and inverters on a daily basis. Our particular focus is on three-phase hybrid inverters, which represent an intelligent, space-saving, and efficient solution for residential photovoltaic systems. In this article, we'll show you what a hybrid inverter actually is, what advantages it offers when combined with a battery storage system, and why it's often the best choice for modern solar projects like those we implement at greenmondi.

What is a hybrid inverter with battery storage?

In traditional PV systems, the inverter plays a central role: It converts the direct current (DC) generated by the solar modules into household-standard alternating current (AC), which can be used in the home or fed into the grid. However, as soon as you want to integrate a power storage system into your system, things become more complex. With conventional technology, a second inverter – the so-called battery inverter – is necessary. However, this results in conversion losses because the power must be converted multiple times. The solution: hybrid inverters. These combine both functions in a single device. The advantage? The generated solar power can flow directly into the storage system and is only converted into alternating current when needed – efficient, space-saving, and cost-effective.

How a hybrid inverter works

A hybrid inverter in a greenmondi system intelligently controls energy flows: If more electricity is produced than consumed during the day, the system automatically charges the connected battery. Only when self-consumption is met and the battery is full does the surplus flow into the public grid. Thanks to this smart control, you can achieve a high proportion of self-consumption while simultaneously reducing your electricity costs. Single-phase or three-phase – which is the right choice? When planning your solar system, our specialist consultants always check which inverter technology is suitable for your individual situation. The following generally applies: • Single-phase hybrid inverters are compact and often sufficient for smaller PV systems. • Three-phase models are more powerful, allow for even load distribution, and are required by law for systems above a certain size (from approximately 4.6 kVA per phase). In our projects, we therefore primarily rely on three-phase hybrid inverters – for maximum future security and grid compliance.

Hybrid inverter comparison – our recommendation. 

We work exclusively with select premium manufacturers. Here are two particularly powerful systems that we frequently install: 

Sungrow Hybrid HV SH series (5.0 – 10RT)

A powerful three-phase inverter with up to 10 kW output, ideal for PV systems up to 25 kWp. Particularly advantageous: two integrated MPP trackers, a wide voltage range, and high charging/discharging performance. Sungrow also offers suitable energy storage solutions, ensuring smooth integration – all from a single source.

Huawei SUN2000 (5/6/8/10KTL-M1 & 12/15KTL-MB0)

Huawei's SUN2000 series hybrid inverters are among the lightest and most compact hybrid devices on the market. They boast extremely high efficiency and offer a wide range of useful features.

These include AI-assisted arc fault protection and precise location of arc faults for rapid resolution. Particularly noteworthy is their seamless compatibility with Huawei's proprietary LUNA2000 energy storage systems – for maximum system efficiency and easy expandability. The devices also feature multiple MPP trackers for flexible module configuration and an intelligent energy management platform.

Why we at greenmondi rely on Sungrow and Huawei
