For installations with a projected lifespan of 15-25 years, this requires purchasing an extended warranty or accepting a higher risk of service costs after the initial warranty period expires. - **Extended warranty period** - Independent sources (igrowattinverter.com, solartechonline.com) indicate that warranty claim processing times range from 23 to 40 days, which is significantly longer than the 7-14 days declared by premium manufacturers (Fronius, SolarEdge). For backup power installations, this could mean a multi-week interruption in UPS functionality. ## About this series Growatt SPE HVM-G2 series are single-phase hybrid inverters designed for grid connection and battery storage integration - making them suitable for both autarky and backup power scenarios. A key feature of this series is the dual output for smart load management and two AC inputs with an automatic transfer switch, facilitating integration with generators and enabling prioritized power supply to selected circuits. Two independent MPPT channels allow optimized operation of two PV strings independently - a significant advantage with panels of varying orientations or seasonal shading. The high European efficiency translates into better energy production under typical climatic conditions in Poland, beyond just laboratory peak performance. Remote monitoring operates via WiFi or 4G and is supported by the PVkeeper platform for local activation. The series is compatible with low-voltage batteries (lithium and lead-acid types), features declared CE certification, and comes with a standard manufacturer's warranty of 5 years in the market. ## Questions ### Does the Growatt SPE HVM-G2 inverter provide backup power during a grid outage? Yes, the SPE HVM-G2 series is a hybrid inverter with integrated backup functionality. Thanks to a built-in transfer switch and two AC inputs, selected circuits (e.g., refrigerator, lighting, router) can be connected to a dedicated output and powered from the battery even when grid voltage is lost. This provides real protection for a home or small business during a blackout. ### Which batteries are compatible with the Growatt SPE HVM-G2? The inverter is designed for low-voltage (48 V) battery systems. It officially supports lithium iron phosphate (LiFePO4) batteries from the Growatt ARK 2.5L-A1, AXE 5.0L-E1, and Hope (14.2L-R1, 5.0L-B1) series, as well as conventional lead-acid batteries. Before purchasing a third-party battery, it is advisable to consult the current compatibility list published by the manufacturer, as it is updated on a regular basis. ### What is the efficiency of the Growatt SPE HVM-G2, and does it matter in the Polish climate? The peak efficiency of the 6000TL model reaches 96.5%; however, under Polish conditions the European efficiency rating is more relevant, as it accounts for frequent cloud cover and partial-load operation. A higher European efficiency translates into a measurably greater annual energy yield than the laboratory peak figure alone would suggest. The SPE HVM-G2 series is designed with temperate climates in mind, making this parameter a meaningful advantage over lower-cost alternatives. ### What are the two MPPT inputs on the Growatt SPE HVM-G2 used for, and when should you take advantage of them? Two independent MPPT inputs allow two separate PV strings to be connected and optimized independently of each other. This is particularly valuable when panels are mounted on roof sections with different orientations (e.g., south- and west-facing) or when one string is periodically shaded by a chimney or dormer window. Without independent MPPT channels, a shaded string would reduce the output of the entire system; here, each string operates at its own maximum power point. ### What warranty does the Growatt SPE HVM-G2 carry, and how does after-sales service work in Poland? The standard manufacturer's warranty for the SPE HVM-G2 series is 5 years. Growatt operates an authorized service network in Poland through MP Solar Group; in the event of a fault, the manufacturer commits to replacing or repairing the unit within a few business days. It is worth confirming warranty terms with the Polish distributor prior to purchase, as some partners offer extended coverage. ### Can the Growatt SPE HVM-G2 be integrated with a generator? Yes, the two AC inputs with a built-in transfer switch allow both the utility grid and a generator to be connected as alternative power sources. The inverter automatically manages power source priority, which is especially useful in areas with an unreliable grid or where a generator is used as seasonal backup. This capability distinguishes the SPE HVM-G2 series from basic hybrid inverters that lack a second AC input. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/spe-3500-7000tl-hvm-g2-datasheet-2511-5818b3ff4ce3.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [SolarEdge SE3500H](https://comparepv.com/inverter/solaredge-se3500h) | 3.5 kW | 99.0% | | 11.4 kg | +3.5 pp efficiency | | [Growatt SPM 3600TL-HU](https://comparepv.com/inverter/growatt-spm-3600tl-hu) | 3.6 kW | 97.6% | 2 | 26.0 kg | +0.1 kW, +2.1 pp efficiency, 15.5 kg heavier | | [Growatt MIN 3600TL-XH](https://comparepv.com/inverter/growatt-min-3600tl-xh) | 3.6 kW | 97.2% | 2 | 10.8 kg | +0.1 kW, +1.7 pp efficiency | | [Growatt MIN 3600TL-XA](https://comparepv.com/inverter/growatt-min-3600tl-xa) | 3.6 kW | 97.2% | | 10.8 kg | +0.1 kW, +1.7 pp efficiency | | [Growatt MIN 3600TL-XH2](https://comparepv.com/inverter/growatt-min-3600tl-xh2) | 3.6 kW | 97.2% | 2 | 10.8 kg | +0.1 kW, +1.7 pp efficiency | | [GoodWe GW3600N-EH](https://comparepv.com/inverter/goodwe-gw3600n-eh) | 3.6 kW | 97.0% | 2 | 17.0 kg | +0.1 kW, +1.5 pp efficiency, 6.5 kg heavier | | [Deye SUN-3.6K-SG04LP1-EU](https://comparepv.com/inverter/deye-sun-3-6k-sg04lp1-eu) | 3.6 kW | 97.0% | 2 | 14.0 kg | +0.1 kW, +1.5 pp efficiency, 3.5 kg heavier | | [Deye SUN-3.6K-SG04LP1-AU](https://comparepv.com/inverter/deye-sun-3-6k-sg04lp1-au) | 3.6 kW | 97.0% | 2 | | +0.1 kW, +1.5 pp efficiency | --- Source: https://comparepv.com/inverter/growatt-spe-3500tl-hvm-24g2
