This eliminates the cost and time associated with inverter replacement, effectively reducing the modernization process from 2-3 days to just 1 day. - **Switching to backup power (less than 10 ms, UPS-level)** - According to the GoodWe datasheet, the switchover time to standalone mode is less than 10 ms, which meets the requirements of online UPS standards. Standard hybrid inverters without UPS certification have switchover times of 20-100 ms, which can cause IT devices to restart or pumps to lose pressure. - **Fanless cooling, IP65, \<35 dB** - Natural convection eliminates moving parts and the risk of fan failure. With a noise level below 35 dB (spec sheet) and an IP65 sealing, it can be mounted both in a garage and outdoors without the need for an additional enclosure. - **Wide range of battery voltage: 85-460 V** - Compatibility with a wide range of HV batteries (including GoodWe Lynx Home F, BYD HVL, and other 48-400 V LFP/NMC batteries) gives installers the flexibility to choose batteries without having to match the nominal voltage to a specific inverter. - **European efficiency: 96.0%, maximum 96.6%** - According to the official GoodWe datasheet, the efficiency of 96.0% is comparable to that of leading AC-coupled competitors (e.g., SolarEdge Energy Hub AC: ~96.5%), which minimizes conversion losses under typical Polish climatic conditions, particularly with frequent partial shading. ### Cons - **Double AC-DC-AC conversion loss** - In an AC-coupled system, energy from the panels passes through two inverters: a string inverter (DC to AC) and a battery inverter (AC to DC to AC during battery discharge). The round-trip efficiency is approximately 92-93% compared to ~95-96% for DC-coupled hybrid systems (e.g., GoodWe ET/EH). This translates to a real annual energy loss of 30-45 kWh. - **Power limited to 6 kW (single-phase)** - The BH series is exclusively available in 3-6 kW variants for single-phase networks. For homes with three-phase connections or peak demand exceeding 6 kW, it is necessary to switch to the BT (three-phase) or hybrid DC-coupled series, which limits the flexibility of retrofitting for larger buildings. ## About this series The GoodWe BH series comprises single-phase inverters of the **retrofit AC-coupled** type, designed for modernizing existing on-grid installations with energy storage - without replacing the previous string inverter. This grid-tie solution features backup functionality: in the event of a grid outage, it switches to backup mode according to the **UPS** standard, enabling critical circuits to continue operating. You won’t find traditional MPPT for panels in the BH inverter, as it operates on the AC side - instead, it intelligently manages battery charging and discharging, increasing self-consumption and limiting energy fed back to the grid. Its high **European efficiency** ensures better performance in weather and load conditions typical of Poland. A major advantage is the **quiet operation without a fan**, compact housing, and simplified installation thanks to Plug & Play solutions and pre-configured communication. Monitoring is handled through the GoodWe platform (app and portal), and integration with storage systems is straightforward - the BH works with various batteries, including GoodWe Lynx Home F and selected market models. This series is particularly suitable for single-family homes and small commercial properties, where quick retrofitting, safety, compliance with grid connection requirements, and manufacturer warranty are key considerations. ## Questions ### Can the GoodWe BH be connected to an existing solar panel installation without replacing the inverter? Yes, this is a key advantage of the BH system. The inverter operates on the AC side, so it can be installed in parallel with an existing string inverter connected to the grid, without requiring replacement. Simply connect the BH to your home AC network and add a high-voltage battery. This solution is ideal when the existing solar panel installation is functioning correctly, and the owner simply wants to add energy storage and a backup power function. ### How quickly does the GoodWe BH switch to backup power in the event of a power outage from the grid? The switching time is less than 10 ms, which meets the standard for UPS systems. In practice, most household appliances will not experience any interruption in power supply. Critical circuits, such as refrigerators, lighting, or routers, can continue to operate without interruption immediately after a power outage, provided that the battery level is sufficient. ### What types of batteries are compatible with the GoodWe BH inverter? BH supports high-voltage batteries (HV) in the range of 85-460 V DC. Officially compatible products include GoodWe Lynx Home F, as well as selected models from other manufacturers. Before purchasing batteries, it is advisable to check the latest compatibility list on the GoodWe website, as it is regularly updated with new models. ### What is the warranty period for the GoodWe BH inverters? The standard manufacturer's warranty is 5 years. GoodWe, as a Tier 1 manufacturer, has a strong market position and an extensive service network in Europe, which provides additional assurance in the event of any claims. The warranty terms require installation by a certified installer and registration of the device on the GoodWe platform. ### Does the GoodWe BH inverter generate a significant amount of noise while in operation? No. The BH is passively cooled, using natural air convection, without a fan. The noise level is below 35 dB, which is equivalent to a quiet office or library. The inverter can be easily installed inside the building, for example, in a hallway, boiler room, or garage, without worrying about annoying noise. ### What capabilities does the GoodWe BH series offer, and which size of home is it suitable for? The BH series is available in 3 kW, 3.6 kW, 5 kW, and 6 kW versions. These models are designed for single-phase installations in single-family homes and small service buildings. For a typical home with a 5-10 kWp PV system and a need for several backup circuits, the 5 or 6 kW version would be sufficient. The device weighs only 15.5 kg, and its dimensions are 354 × 433 × 147 mm, making it easy to mount on a wall. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/1307775769648338d674d43-2346df3186b4.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [SolarEdge SE3000H](https://comparepv.com/inverter/solaredge-se3000h) | 3 kW | 98.8% | | 12.0 kg | +2.8 pp efficiency, 3.5 kg lighter | | [Growatt MOD 3000TL3-HU](https://comparepv.com/inverter/growatt-mod-3000tl3-hu) | 3 kW | 97.8% | 2 | 19.0 kg | +1.8 pp efficiency, 3.5 kg heavier | | [Growatt SPM 3000TL-HU](https://comparepv.com/inverter/growatt-spm-3000tl-hu) | 3 kW | 97.6% | 2 | 26.0 kg | +1.6 pp efficiency, 10.5 kg heavier | | [Huawei SUN2000L-3KTL](https://comparepv.com/inverter/huawei-sun2000l-3ktl) | 3 kW | 97.6% | 2 | 10.6 kg | +1.6 pp efficiency, 4.9 kg lighter | | [Growatt MOD 3000TL3-XH](https://comparepv.com/inverter/growatt-mod-3000tl3-xh) | 3 kW | 97.5% | 2 | 12.5 kg | +1.5 pp efficiency, 3.0 kg lighter | | [Huawei SUN2000-3KTL-L1](https://comparepv.com/inverter/huawei-sun2000-3ktl-l1) | 3 kW | 97.3% | 2 | 12.0 kg | +1.3 pp efficiency, 3.5 kg lighter | | [Growatt MIN 3000TL-XH](https://comparepv.com/inverter/growatt-min-3000tl-xh) | 3 kW | 97.1% | 2 | 10.8 kg | +1.1 pp efficiency, 4.7 kg lighter | | [Growatt MIN 3000TL-XA](https://comparepv.com/inverter/growatt-min-3000tl-xa) | 3 kW | 97.1% | | 10.8 kg | +1.1 pp efficiency, 4.7 kg lighter | --- Source: https://comparepv.com/inverter/goodwe-gw3k-bh
