Enphase launched its IQ9N series microinverter with a maximum rated power output of 427 VA and a maximum conversion efficiency of 97.95%
The company also showcased the latest IQ Battery G5 series modular vertically stacked 30 kWh home storage system that features 6 battery units, each of 5 kWh capacity, and an IQ9N series microinverter
Also on display was a bidirectional DC-coupled EV charger, the IQ Bidirectional EV charger, which is scheduled to be commercially available by the end of 2026
Today’s residential energy ecosystem, including a hybrid inverter, storage, PV, EV charger, and home appliances, is increasingly connected with a digital energy management system (EMS), enabling energy flexibility. US-based Enphase Energy, drawing on 20 years of experience in microinverter or module-level power electronics (MLPE) manufacturing, showcased its latest products for these applications at Intersolar Europe 2026.
Stephan Ostermann, Senior Manager of Training for EMEA at Enphase, gave the TaiyangNews team a tour of the company’s showcases during a booth visit.
On the microinverter side, Ostermann highlighted the latest IQ9N series product. Unlike the earlier IQ8 series, its bidirectional inverter is equipped with Gallium Nitride (GaN)-based power switches that offer faster switching speed and cooler operation within a 212 × 175 × 30.20 mm (L × W × H) enclosure. As a result, Ostermann said, it can deliver higher power output. Its built-in software can be configured in line with regional distribution voltage levels (e.g., Europe and the US), facilitating global compatibility. This software is embedded into a small, in-house-made chip (see Enphase Promotes GaN-Based Microinverter At Intersolar).
The company also showcased its latest residential AC-coupled energy storage system (ESS), IQ Battery G5. Ostermann noted that the battery comprises up to 6 battery units, each with 5 kWh of capacity and an IQ9N microinverter, mounted on top of each other. This distributed storage configuration with a pack-level built-in microinverter reduces the DC bus voltage compared to conventional counterparts, enhancing the fire safety quotient. It also offers a cumulative storage capacity of 30 kWh relative to the IQ Battery G3’s 5 kWh within the same footprint.
This product is expected to be commercially available in early 2027, while the former is widely available across Europe and the US, Ostermann added.
Also on display was the company’s DC-coupled IQ Bidirectional EV charger, which can switch between Vehicle-to-Grid (V2G) and Vehicle-to-Home (V2H) modes. It uses excess PV generation to charge the vehicle battery, which can be reused as an emergency backup during a grid outage as part of an integrated home energy ecosystem. He added that its storage capacity can support grid stability after receiving a signal from distribution companies. It is slated to be commercially available by the end of 2026.
