This means that critical devices connected to the system (e.g., NAS, routers, medical equipment) will not lose power during a network outage - the 20 ms threshold exceeds the tolerance of most consumer electronics. - **Wide battery compatibility (LV)** - The EM series works with at least 4 different LV battery families, confirmed by the manufacturers: BYD Battery-Box (LVL, LV5.0+), LG RESU (3.3-12 kWh), Pylontech (US2000/US3000/US5000), and Dyness POWERBOX F. This gives the installer the flexibility to choose a storage system without being tied to a single supplier. - **Tier-1 manufacturer / bankable since 2010** - GoodWe is listed on BNEF's Tier-1 bankable inverter manufacturers list, which is a requirement for financial institutions to accept their inverters in both residential and commercial projects. The stability of the company, founded in 2010 and listed on the Shanghai Stock Exchange, reduces the risk of lacking after-sales support within a 10-15 year timeframe. - **Export control (zero export)** - The built-in zero export function allows you to limit or completely block the export of energy to the grid without the need for an external meter. This is particularly important in prosumer installations, where an agreement with the energy supplier (OSD) may restrict the export power or require its monitoring. - **Support for up to 2 independent MPPT (Maximum Power Point Tracking) systems within a single-phase device.** - Having two MPPT trackers in a 3-5 kW single-phase inverter allows you to connect PV strings with different orientations or exposures without losing efficiency on less sun-exposed sides. In the case of single-phase LV inverters from many manufacturers, the limit is typically 1 MPPT. ### Cons - **SEMS application - rating of 3.57/5 (based on 3,900 reviews)** - The SEMS Portal mobile application (iOS/Android) has an average rating of 3.57 out of 5 in app stores (data: December 2025, ~3900 reviews). Users report issues with login after updates, freezing when viewing monthly charts, and a lack of the ability to filter data by date. Compared to competitors (e.g., Fronius Solar.web, SolarEdge mySolarEdge), the UX remains below market expectations. - **The battery charging power is only 2.3 kW.** - The maximum charging/discharging power for the EM series batteries is 2.3 kW, which, when combined with a 5 kW AC variant, means that the inverter cannot simultaneously power the entire house at full capacity and charge the battery at its maximum speed. The competitive ES G2 series (similar price range, same manufacturer) offers a higher charging current. - **Standard 5-year warranty with extended warranty options** - The standard warranty is 5 years, but extending it to 10 years requires meeting the conditions of the GoodWe PLUS+ program (including registration by a certified installer and a specific period of time since installation). Some competitors in this segment (e.g., SolarEdge, Huawei) offer a standard 12-year warranty or without additional registration requirements. ## About this series The GoodWe EM series are single-phase hybrid (LV) inverters, intelligently managing energy flow in on-grid installations: prioritizing home supply, then battery charging, with excess available for grid export. Depending on the variant, they feature up to **2 MPPT**, facilitating the design of rooftop systems with different orientations or partial shading - each tracker optimizes the PV string performance independently. The high European efficiency translates to a significantly better yield under typical climatic conditions in Poland, beyond laboratory settings. The EM offers features crucial for self-consumption, such as **export control (zero export)** and rapid switching to UPS-style backup power supply, ensuring critical circuits remain operational during grid outages. Monitoring is conducted via the SEMS app and connectivity options including WiFi or WiFi/LAN, allowing you to view production, consumption, and battery performance. This series is an excellent choice for modern home installations with energy storage, and meets requirements for safety, enclosure integrity, and warranty (standard 5 years, extendable to 10 years under the GoodWe PLUS+ program conditions). ## Questions ### What power options are available in the GoodWe EM series, and how many MPPT trackers does it offer? The GoodWe EM series includes models with output power ranging from 3 to 5 kW, designed for single-phase residential installations. Depending on the model, up to 2 independent MPPT (Maximum Power Point Tracking) systems are available, allowing for the connection of strings of panels facing different directions or partially shaded sections of a roof. Each MPPT system operates independently, maximizing the overall energy yield. ### What batteries are compatible with the GoodWe EM inverter? The GoodWe EM inverter is officially compatible with GoodWe Lynx Home U series low-voltage batteries. The maximum charging and discharging current is 50 A, which translates to an energy exchange power with the battery of approximately 2.3 kW. To maintain the full warranty, only batteries listed on the official list of approved GoodWe batteries should be used. ### How quickly does a GoodWe EM switch to backup power when the main power supply fails? The GoodWe EM is equipped with a UPS class switching function, which activates the backup power in less than 10 ms in the event of a power outage. This extremely short switching time means that sensitive devices connected to the backup circuit, such as routers, NAS devices, or medical equipment, practically experience no interruption in power supply. ### What is the "zero export" function in GoodWe EM, and when is it beneficial to enable it? The "zero export" function, also known as export control, allows you to limit or completely block the transmission of excess energy back to the electricity grid. This is useful in cases where distribution agreements prohibit export, when there is no bidirectional meter, or when the investor wants to maximize self-consumption. The inverter continuously monitors power consumption in the home and dynamically adjusts the operation of the panels to stay within the set export limit. ### What is the warranty on the GoodWe EM inverters, and how can it be extended? The standard manufacturer's warranty for the GoodWe EM series is 5 years. This warranty can be extended to 10 years under the GoodWe PLUS+ program, provided certain conditions are met, including device registration and installation by a certified installer. GoodWe is a Tier 1 manufacturer, which signifies the company's financial stability and the real possibility of enforcing the warranty throughout its duration. ### Can the GoodWe EM inverter be installed outdoors? Yes, the GoodWe EM series enclosure has an IP65 rating, which means complete protection against dust and resistance to water jets. The inverter is suitable for both indoor (e.g., garage, boiler room) and outdoor wall mounting, provided that it is protected from direct sunlight or rain from the side. This reduces the risk of overheating and extends the lifespan of the device. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/97790422164dcc4eec3894-bd274913d1e6.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [SolarEdge StorEdge AC Coupled Single Phase Inverter (HD‑Wave) – SE5000H / H5000SE](https://comparepv.com/inverter/solaredge-storedge-ac-coupled-single-phase-inverter-hd-wave-se5000h-h5000se) | 5 kW | 99.0% | | 9.0 kg | +2.0 pp efficiency, 8.0 kg lighter | | [SolarEdge SE5000H](https://comparepv.com/inverter/solaredge-se5000h) | 5 kW | 99.0% | | 12.0 kg | +2.0 pp efficiency, 5.0 kg lighter | | [Huawei SUN2000L-5KTL](https://comparepv.com/inverter/huawei-sun2000l-5ktl) | 5 kW | 98.0% | 2 | 10.6 kg | +1.0 pp efficiency, 6.4 kg lighter | | [Growatt MOD 5000TL3-HU](https://comparepv.com/inverter/growatt-mod-5000tl3-hu) | 5 kW | 97.8% | 2 | 19.0 kg | +0.8 pp efficiency, 2.0 kg heavier | | [Huawei SUN2000-5KTL-L1](https://comparepv.com/inverter/huawei-sun2000-5ktl-l1) | 5 kW | 97.8% | 2 | 12.0 kg | +0.8 pp efficiency, 5.0 kg lighter | | [Ginlong Solis RHI-3P5K-HVES-5G](https://comparepv.com/inverter/ginlong-solis-rhi-3p5k-hves-5g) | 5 kW | 97.7% | 2 | 25.1 kg | +0.7 pp efficiency, 8.1 kg heavier | | [Growatt SPM 5000TL-HU](https://comparepv.com/inverter/growatt-spm-5000tl-hu) | 5 kW | 97.6% | 2 | 26.0 kg | +0.6 pp efficiency, 9.0 kg heavier | | [Growatt MOD 5000TL3-XH](https://comparepv.com/inverter/growatt-mod-5000tl3-xh) | 5 kW | 97.5% | 2 | 12.5 kg | +0.5 pp efficiency, 4.5 kg lighter | --- Source: https://comparepv.com/inverter/goodwe-gw5048-em
