  • Hoymiles’ Hi-series microinverters with micro storage system are targeted at European residential users or prosumers 

  • Its HiFlow microinverter is built for balconies, gardens, or small rooftop installations, while HiFlow Pro supports complex rooftop installations 

  • The HiBattery AC series battery unit provides flexible energy storage options when paired with microinverters 

With the European distributed generation (DG) market in focus, Hoymiles, a provider of Module-Level Power Electronics (MLPE) solutions, has introduced its latest Hi Series products in Germany. 

This product series features 2 types of microinverters and an AC-coupled battery unit.  

According to the company, the latest HiFlow 800 microinverter, when paired with up to 520 W PV modules, while keeping the input terminal voltage (Voc) under 100 V, delivers a power output (1-phase) of up to 800 W. Equipped with a 16 A MPPT channel, up to 99.8% of incident sunlight is converted to DC power, with up to 97% of this output inverted to AC power by the microinverter. This is designed for balcony, garden, or small rooftop applications. 

For complex rooftop installations with PV modules installed in different directions, which are prone to partial shading, the company offers the HiFlow Pro series microinverter. The company claims its 2 MPPT channels optimize solar harvesting with a tracking efficiency of up to 99.8%. It features a rated power output (AC) range of 300 W to 2,000 W, serving a variety of household demands. 

Users can install Hoymiles’ S-Miles Home app on their mobile in under 1 minute to monitor and control both the above-mentioned systems in real time. 

For hybrid micro-storage applications, these microinverters can be connected with the HiBattery AC battery in an AC-coupled configuration. Built with automotive-grade lithium-iron-phosphate (LFP) batteries, it stores or discharges up to 1.92 kWh of energy. This automotive-grade battery supports frequent charging/discharging with up to 86% round-trip efficiency (RTE) for up to 6,000 cycles, in cases of a grid outage or failure in the on-grid configuration. This micro storage system also supports off-grid configuration. In addition, its fanless cooling design reduces operational noise levels to below 17 dB, making it suitable for residential applications. 

Unlike standard hybrid ‘all-in-one' systems, it requires no rewiring or inverter replacement for capacity expansion, says Hoymiles. Users can plug the unit into a standard household socket, allowing it to be placed anywhere in the home. From an operational perspective, in addition to self-consumption and an optional zero power export function, its bidirectional converter technology enables time-of-use (TOU) charging when electricity prices are low and discharging when prices peak.
