According to GoodWe's official materials, the installation time is significantly shorter compared to a traditional inverter + separate battery setup, and the wall space required is smaller - a significant advantage in typical Polish boiler rooms. - **UPS switching time \<4 ms** - The time to switch to emergency mode is less than 4 ms (data from GoodWe), which is sufficient for computer equipment, routers, and refrigerators. According to EN 62040-3, systems with a switching time of less than 20 ms are classified as VFI - the system in question meets this requirement. - **Peak efficiency: 97.6%** - The maximum CEC/Euro efficiency of the GoodWe EN series (models 3-6 kW, as per the datasheet) reaches 97.6%, placing it in the top quartile of single-phase hybrid systems on the European market, exceeding the typical 96-97% efficiency range of mid-range competitors (e.g., Sofar Solar HYD, Solis RHI). - **200% oversizing of PV + 2-4 MPPT** - The allowable DC overload up to 200% of AC power allows for maximizing production with smaller panels (flat curve morning/evening). Models with 3-6 kW offer 2 MPPT (Maximum Power Point Tracking), while higher-power models offer 4 MPPT, enabling independent operation of different-oriented or partially shaded panels. - **Tier-1 bankable + 10-year guarantee** - GoodWe has been featured on BNEF's Tier-1 list for many years (a recognized manufacturer). When installed by a certified installer, GoodWe offers a 10-year system warranty - longer than the standard 5-7 years offered by some competitors in the all-in-one segment. ### Cons - **Lack of AFCI in the single-phase version** - The single-phase ESA does not include arc fault detection (AFCI) functionality (this feature is only available in the three-phase ESA 5-30 kW with AFCI 3.0). As installation standards in the EU become stricter (EN 62443, building regulations), the lack of AFCI may pose a challenge for certain projects or require additional external protection. - **Limiting to a single-phase connection** - The ESA series (3-10 kW) is exclusively designed for single-phase networks. Households with a 3-phase connection (becoming increasingly common, especially in new buildings and with heat pumps >3.5 kW) must choose either the ESA series or another GoodWe series (e.g., ET), which prevents direct use of this series. ## About this series The GoodWe ESA series is a **single-phase hybrid all-in-one solution**, combining a PV inverter and energy storage in one factory-assembled, pre-wired enclosure. This design simplifies installation, while the entire unit occupies less space than a traditional inverter-plus-battery setup. The ESA is ideal for homes prioritizing self-consumption, energy storage operation, and backup power - the system features **UPS switching**, enabling rapid power supply to selected circuits during grid outages. The **2 MPPT** capability enhances performance by optimizing energy harvest from panels with varying roof tilts, unequal string lengths, or partial shading. Its **high European efficiency** ensures superior energy production under typical operating conditions in Poland, beyond ideal laboratory settings. Monitoring is accessible via the SEMS portal and app, with communication options including WiFi or wired solutions (depending on configuration). ESA is compatible with LFP batteries, and its weatherproof enclosure facilitates indoor or outdoor mounting. In practice, this series is suited for demanding residential and small business installations, where energy storage and independence are key priorities. ## Questions ### What is the warranty for the GoodWe ESA system? GoodWe offers a 10-year warranty on the ESA 10 series, covering both the inverter and battery modules. This warranty is conditional, requiring product activation through the SEMS portal. As GoodWe is a Tier 1 manufacturer, the risk associated with warranty service is lower compared to smaller brands. The LFP batteries used in the ESA also have a naturally long lifespan, typically several thousand cycles. ### How quickly does the GoodWe ESA switch to backup power in the event of a power outage? The time it takes for the ESA to switch to off-grid mode is less than 4 milliseconds, which is comparable to that of a UPS. In practice, this means that connected devices - such as computers, routers, and essential appliances - will not experience any interruption in power supply. This is a significant advantage over standard grid-tie inverters, which completely cease operation when the grid fails. ### What distinguishes the GoodWe ESA from a system consisting of a separate inverter and a separate battery? ESA is a complete solution - the PV inverter, charging converter, and LFP battery are all housed in a single, ready-to-install unit. Installation takes up less space on the wall and is quicker than connecting individual devices. A disadvantage is the limited flexibility in choosing components - it's not possible to freely select a battery from a different manufacturer; you must remain within the GoodWe ecosystem. ### What are the power and capacity options available for GoodWe ESA batteries? The ESA single-phase series includes models with power outputs ranging from 3 to 10 kW (3, 3.6, 5, 6, 8, and 10 kW models). The energy storage capacity can be configured from 5 to 48 kWh - the system allows for the connection of multiple LFP battery modules. A three-phase version with power outputs of 5-30 kW and capacities up to 108 kWh is also available, designed for larger facilities. ### Can a GoodWe ESA be remotely monitored using a phone? Yes, ESA collaborates with the SEMS (Smart Energy Management System) platform from GoodWe - it is accessible both through a web browser and a mobile app. The portal displays current PV production, battery state of charge, self-consumption, and grid interaction. Connection is made via WiFi or, optionally, through a wired connection. SEMS is considered one of the most transparent monitoring solutions on the market. ### Can the GoodWe ESA be mounted outdoors? Yes, the ESA enclosure has an IP65 level of protection, which allows for installation outdoors - for example, on a garage wall or warehouse - without the need for additional covering. The system is designed to withstand typical weather conditions. Outdoor mounting saves space inside the house, but it is important to avoid prolonged, direct sunlight exposure to prevent overheating of the batteries. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/GW-ESA-Datasheet-EN-8e26b99dca73.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, 35.0 kg lighter | | [SolarEdge SE5000H](https://comparepv.com/inverter/solaredge-se5000h) | 5 kW | 99.0% | | 12.0 kg | +2.0 pp efficiency, 32.0 kg lighter | | [Huawei SUN2000L-5KTL](https://comparepv.com/inverter/huawei-sun2000l-5ktl) | 5 kW | 98.0% | 2 | 10.6 kg | +1.0 pp efficiency, 33.4 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, 25.0 kg lighter | | [Huawei SUN2000-5KTL-L1](https://comparepv.com/inverter/huawei-sun2000-5ktl-l1) | 5 kW | 97.8% | 2 | 12.0 kg | +0.8 pp efficiency, 32.0 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, 18.9 kg lighter | | [Growatt SPM 5000TL-HU](https://comparepv.com/inverter/growatt-spm-5000tl-hu) | 5 kW | 97.6% | 2 | 26.0 kg | +0.6 pp efficiency, 18.0 kg lighter | | [Growatt MOD 5000TL3-XH](https://comparepv.com/inverter/growatt-mod-5000tl3-xh) | 5 kW | 97.5% | 2 | 12.5 kg | +0.5 pp efficiency, 31.5 kg lighter | --- Source: https://comparepv.com/inverter/goodwe-gw5048-esa
