New High-Efficiency PV Inverter Series Debuts in Munich, Empowering Residential and Small Commercial Solar Adoption
Munich, Bavaria – September 2, 2025
A leading European renewable energy technology provider today launched its latest TP Series photovoltaic (PV) inverters at a press event in Munich, targeting residential and small commercial solar systems with a focus on efficiency, flexibility, and grid compatibility. The series, spanning 5kW to 10kW (TP5KH to TP10KH), arrives as Germany’s solar market continues to grow—with the Federal Network Agency reporting a 15% increase in residential installations in H1 2025—and addresses demand for reliable, high-performance energy conversion solutions.
The TP Series stands out for its industry-leading efficiency: the top-tier TP10KH model achieves a maximum PV-to-AC conversion efficiency of 97.8%, while all models boast a minimum European Efficiency (EE) of 96.9%. This translates to more energy harvested from solar panels and lower electricity bills for users, a critical factor as German households face rising grid energy costs (up 8% year-over-year in 2025).
“Our goal with the TP Series was to create a versatile inverter that works seamlessly with both new and existing solar setups,” said Lisa Müller, Product Manager at the provider. “We’ve optimized for high efficiency across all power ranges, and the ability to support both lithium-ion and lead-acid batteries gives homeowners flexibility as they transition to energy storage.”
The inverters also excel in grid integration: they support a wide nominal grid voltage range (260V-450V adjustable) and comply with strict European grid codes (including VDE 4105 and EN 50494). A maximum total harmonic distortion (THD) of <5% ensures clean power delivery, while anti-islanding protection and AC overcurrent protection meet IEC/EN 62109-2 safety standards—critical for gaining approval from German grid operators.
For backup power, the series offers nominal output power matching the grid-tied capacity (5kW to 10kW), with a transfer time of <10ms to ensure uninterrupted supply during outages. This feature is particularly appealing in Bavaria, where extreme weather events (e.g., winter storms) have caused a 20% increase in grid disruptions since 2020.
Munich-based solar installation firm SolarTech Solutions was one of the first to test the TP Series, installing a TP8KH model (8kW) for a family in the suburban neighborhood of Grünwald. “The wall-mount design saved space on the garage wall, and the RS485/CAN communication interface made it easy to integrate with the home’s battery management system (BMS),” said Michael Schmidt, Lead Installer at SolarTech. “We also appreciate the optional Wi-Fi/LAN connectivity—our technicians can monitor performance remotely, which cuts down on service calls.”
Anna Becker, the Grünwald homeowner who installed the TP8KH, shared her experience after a week of use: “The LCD display on the inverter shows real-time solar production and battery level, which is helpful for tracking our energy use. During a 2-hour outage last weekend, the backup power kept our fridge and Wi-Fi running—something we never had with our old inverter. The 10-year warranty (we opted for the extended plan) also gives us peace of mind.”
The provider plans to roll out the TP Series across Europe in Q4 2025, with a focus on Germany, France, and Italy—markets where residential solar installations are expected to grow by 12-15% annually through 2030. Pricing starts at €1,800 for the TP5KH (5kW) and goes up to €3,200 for the TP10KH (10kW), competitive with similar products in the European market.
“With the EU’s 2030 Renewable Energy Target requiring 42.5% of energy from renewables, we see strong demand for reliable inverters that can scale with homeowners’ needs,” Müller added. “The TP Series is our response to that demand—an efficient, safe, and flexible solution that helps families take control of their energy future.”
