The GoodWe EH PLUS+ series are single-phase hybrid string inverters designed for domestic PV installations, intended to operate both with the grid and with an energy storage system. The Battery Ready concept distinguishes them - you can start with classic grid-connected operation, adding a storage unit later by activating the storage function via a code. This practical solution is ideal for individuals planning to modernize their installations in Poland.
Two independent tracking strings for the maximum power point, i.e., 2 MPPT, facilitate optimization yields for panels at different roof orientations and partial shading, translating into genuinely more stable production throughout the day. The high European efficiency means the inverter is effective under typical working conditions in our climate, not just in a laboratory setting.
A notable advantage is the switching to emergency power supply of UPS class along with intelligent load control and peak shaving functions. Monitoring is done through the SEMS platform - with an app and remote diagnostics - and for communication, you can use, among other things, WiFi or Ethernet. The EH PLUS+ works with high-voltage lithium-ion batteries, such as the Lynx Home F PLUS+ series, and its IP65-rated enclosure with built-in DC surge protection enhances installation safety.

Pros and cons
The inverter immediately functions as a grid-tied system, and the energy storage function is activated through a simple code without requiring any hardware changes. This represents a real cost saving for prosumers who plan to expand their installations in stages - it eliminates the need to purchase batteries or replace equipment in advance.
Automatic switching to battery power within 10 ms meets the definition of an uninterruptible power supply (UPS) according to IEC 62040, which protects sensitive devices (computers, NAS, heat pumps) from brief power outages. Standard off-grid inverters typically switch within 20-100 ms.
Two independent MPPT controllers can handle up to 16A of input current each, allowing for the connection of 430+ Wp modules and DC oversizing up to 150% of AC power. This is a significant advantage for installations in areas with varying orientations or partial shading.
A free extension of the warranty from 5 to 10 years is available when the system is installed by a certified installer of the GoodWe PLUS+ program. Most competitors in this price segment (e.g., Sofar, Deye) typically offer a standard 5-year warranty, with an additional 10-year warranty available for a fee.
GoodWe is listed on Bloomberg NEF's Tier-1 bankable list, and according to a 2022 study, it was the third most popular inverter in Poland. This translates to the availability of certified technicians and spare parts - which is crucial for a 10-year operating cycle.
The series is limited to power outputs up to 6 kW in a single-phase configuration, which excludes its use in installations exceeding this limit. Customers requiring power above 6 kW must opt for the three-phase ET PLUS+ series, which restricts the flexibility of selecting products within a single product line.
Users on industry forums (elektroda.pl, 2024-2025) report outdated Polish translations of the SEMS application, occasional loss of settings after updates, and time synchronization errors. This is not a hardware issue, but it can reduce the comfort of daily monitoring.
