GoodWe unveils major firmware upgrade with BayWa r.e., taking its inverters to a new level of efficiency in Czechia

Last year, new brands of photovoltaic components appeared on the Czech market, a logical response to increased demand for home solar power plants. This led to increased competition in Czechia and Slovakia, which was also felt by leading inverter manufacturer GoodWe.

Thanks to recent innovations and a firmware update carried out in cooperation with BayWa r.e., GoodWe remains one of the most attractive choices for both customers and installation companies. With the new firmware, the brand’s technical advantages are beyond question.

This important firmware update brings a range of new and improved features. One of them is the ability of the 10 kW inverter model (GoodWe 10K-ET Plus) to handle up to 125% overload on the AC side, meaning it can deliver up to 4,1 kW of power to a single phase. Even the 8kW version allows up to 150% overload, meaning it can deliver up to 4,1 kW to a single phase.

For end customers, this means that when a larger appliance is switched on on a single phase, the inverter can use this overload capacity to provide the required energy without drawing power from the distribution grid. This is great news for owners of solar power plants with GoodWe inverters.

The changes introduced by the new DSP 11 and ARM 27 firmware for GoodWe ET Plus series 8 and 10 kW inverters are particularly noteworthy. In addition to being able to deliver up to 4,1 kW of power to a single phase, the control response time has also been reduced to just 3 seconds!

The inverter’s fast response to changes in load means more efficient use of self-generated energy in the home and lower electricity imports from the grid.

One of the best things for existing GoodWe customers is that this update is not limited to new inverters. Older inverters purchased from 1. 1. 2022 will also receive the firmware update free of charge.

This significant update takes the quality and performance of GoodWe inverters to a new level, while increasing value for customers at a lower price.

Another important step is the offering of the complete GoodWe Eco Smart Home solution, which includes inverters, batteries and electric vehicle chargers. ET Plus series inverters up to 10 kW paired with Lynx Home F batteries now come with an extended 10-year warranty.

With this innovative approach, GoodWe clearly demonstrates that it continues to advance photovoltaic technology and strengthen its leading position in the market.

Why is GoodWe the best choice?

GoodWe has been number one on the market for 7 years. GoodWe was the first company to launch a three-phase asymmetric hybrid inverter that works with high-voltage batteries.

GoodWe provides technical support in Czech thanks to its cooperation with BayWa r.e., GoodWe’s official distributor, which has warehouses in the Czech Republic. This gives installation companies access to flexible technical support and service.

GoodWe products are highly compatible with batteries from various brands, giving installers confidence when choosing batteries.

ET Plus series inverters have a built-in programmable switching contact that allows an additional load, such as a water heater, to be connected when surplus energy is being fed into the grid.

Thanks to BayWa r.e.’s free monitoring system, it is possible to detect installation faults and ensure the power plant operates smoothly.

GoodWe keeps development and testing in-house and works with BayWa r.e.’s technical support team to adapt to the regulations of the Czech and Slovak markets, for example by ensuring the correct phase measurement settings for inverters.
