This enables direct support of motors, pumps, and compressors with high inrush currents without oversizing the inverter - a technological advantage that high-frequency inverters in the same price class cannot replicate. - **Unity Output Power Factor (PF = 1.0)** - The full 6,000 W is delivered to the load regardless of its inductive character. The manufacturer rates output PF at 1.0, eliminating the hidden internal losses inherent to off-grid inverters with PF = 0.8, which effectively cap usable real power at approximately 4.8 kW at the same apparent-power rating. - **Parallel Operation of Up to 6 Units (36 kW)** - The series supports paralleling up to 6 units, allowing an off-grid system to scale to 36 kW without replacing the central component. By comparison, the SMA Sunny Island - a leading competitor in this class - requires dedicated communication hardware to parallelize even two units. - **Multi-Source Input: PV, Grid, Generator, Battery** - The inverter simultaneously accepts PV (up to 250 V DC), a 48 V battery bank (Li-ion and PbA), an AC grid connection, and a diesel generator, with automatic source prioritization. Compatibility with both battery chemistries - lithium-ion and lead-acid - increases storage configuration flexibility and lowers the investment entry threshold. - **Remote Monitoring via Wi-Fi / GPRS** - The integrated Wi-Fi/GPRS communication module enables direct integration with the Growatt ShinePhone platform without an additional datalogger. This allows real-time remote monitoring of system parameters and over-the-air firmware updates, reducing on-site service costs. ### Cons - **IP20 Rating - No Dust or Moisture Protection** - The IP20 ingress protection rating precludes outdoor installation or placement in damp environments without an additional sealed enclosure. Competing hybrid inverters in this class - such as the Victron Quattro and Sol-Ark 12K - offer IP21 to IP65 ratings, which represents a significant design constraint in temperate climates with high seasonal humidity. - **38.5 kg Weight - Challenging Installation Logistics** - The low-frequency transformer raises the unit weight to 38.5 kg, compared to approximately 17-20 kg for high-frequency inverters of equivalent power (e.g., Deye SUN-6K-SG03LP1). Installation requires at least a two-person crew and a robust mounting structure, adding to overall BoS costs. - **Peak Efficiency 93-94% vs. High-Frequency Competitors** - The rated peak efficiency of 93-94% is lower than that of leading high-frequency inverters (e.g., Fronius Symo GEN24: 98%, SolarEdge StorEdge: 97.6%). In a typical 6 kW system operating 2,000 hours per year, a 3-4 percentage-point efficiency gap translates to a real annual energy loss of approximately 360-480 kWh. - **Growatt Not Listed as a Tier-1 Bankable Manufacturer (BNEF)** - Growatt does not appear on the BloombergNEF bankable inverter manufacturers list, which may complicate access to non-recourse project financing and narrows the pool of institutional investors willing to accept the equipment as collateral. For commercial installations, additional brand justification may be required by insurers and lenders. ## About this series Growatt SPF 6000T DVM-G2 is a **low-frequency off-grid inverter with an integrated transformer**, designed for reliable power where stability and resilience to demanding loads are crucial, such as pumps, motors, and equipment with high surge currents. This is an excellent choice for off-grid homes, recreational facilities, farms, and backup power installations, where energy sources can include PV, batteries, the grid, or a generator. In practice, you get **2 independent MPPTs**, which simplifies the design of systems in shaded conditions or with different roof orientations-each string operates closer to its maximum potential. High efficiency in typical European conditions means less losses in daily operation and more predictable energy production during transitional seasons. A plus is also **remote monitoring via WiFi or GPRS** and service tools for local activation. The devices work with energy storage systems (including lithium and lead-acid types) and allow system expansion through **parallel operation**. Complete documentation, certificates, and warranty terms are available, depending on distribution. ## Questions ### Is the Growatt SPF 6000T DVM-G2 suitable for powering a submersible pump or electric motor? Yes, the SPF 6000T DVM-G2 is specifically designed for loads with high inrush currents. Thanks to its built-in low-frequency transformer and a peak power rating of 18,000 VA - three times its nominal output of 6,000 W - the inverter starts submersible pumps, electric motors, and compressors without issue. This is a critical advantage over lighter high-frequency inverters, which frequently fail to handle the current spikes that occur during motor startup. ### How does the Growatt SPF 6000T DVM-G2 differ from standard high-frequency off-grid inverters? The SPF 6000T DVM-G2 is a low-frequency inverter with a physical transformer inside the unit. This translates to superior overload tolerance (peak power of 18,000 VA, compared to the typical 200-300% for 20 ms found in HF models), greater durability under inductive loads, and a more stable sine wave output. The tradeoffs are a higher unit weight - approximately 38.5 kg - and a higher upfront cost; however, in demanding industrial and agricultural applications, this investment pays off. ### What is the warranty on the Growatt SPF 6000T DVM-G2 inverter? The standard manufacturer's warranty for the SPF 6000T DVM-G2 is 5 years. Actual terms may vary depending on the distributor and country of purchase - some resellers offer the option to extend warranty coverage. It is worth verifying these conditions before purchasing, as Growatt is not a Tier 1 manufacturer and post-warranty service depends on the availability of a local distributor. ### How many SPF 6000T DVM-G2 units can be connected in parallel, and what total power output can be achieved? In a single-phase configuration, up to 6 SPF 6000T DVM-G2 units can be connected in parallel, delivering a combined output of up to 36 kW. This makes the solution ideal for farms, recreational facilities, or systems with growing energy demands. Scaling the system does not require replacing existing equipment - simply adding additional units is sufficient. ### Which battery types are compatible with the Growatt SPF 6000T DVM-G2? The inverter supports lithium-ion batteries (including LiFePO4), flooded lead-acid, AGM, and gel batteries. The nominal battery bank voltage is 48 V. Charging parameters can be adjusted to match the specific cell chemistry via the control panel or the companion app, allowing the energy storage system's lifespan to be optimized regardless of the chosen battery technology. ### Does the Growatt SPF 6000T DVM-G2 operate during winter under Polish climate conditions, and how does it handle low temperatures? The SPF 6000T DVM-G2 is rated for operation across a temperature range of -20 °C to +50 °C, making it fully suitable for year-round use in the Polish climate. The built-in low-frequency transformer is inherently resilient to freezing temperatures; however, during severe cold spells, attention must be paid to battery temperature, as it is the batteries - not the inverter itself - that most commonly become the limiting factor of the system in winter. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/SPF-6000T-DVM-G2-Datasheet-410aae02a70f.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Growatt SPF 6000T DVM](https://comparepv.com/inverter/growatt-spf-6000t-dvm) | 6 kW | | | 52.0 kg | 13.5 kg heavier | | [Growatt SPF 6000T DVM-MPV](https://comparepv.com/inverter/growatt-spf-6000t-dvm-mpv) | 6 kW | | | 52.0 kg | 13.5 kg heavier | | [Growatt SPF 6000 ES Plus](https://comparepv.com/inverter/growatt-spf-6000-es-plus) | 6 kW | | 2 | 13.5 kg | +1 MPPT, 25.0 kg lighter | | [SMA Solar SI8.0H-13](https://comparepv.com/inverter/sma-solar-si8-0h-13) | 6 kW | | | 63.0 kg | 24.5 kg heavier | | [Easun Power ISolar MLV 6KW](https://comparepv.com/inverter/easun-power-isolar-mlv-6kw) | 6 kW | | | 30.0 kg | 8.5 kg lighter | | [PowMr POW-HVM6.2M-48V-N](https://comparepv.com/inverter/powmr-pow-hvm6-2m-48v-n) | 6.2 kW | | | 10.0 kg | +0.2 kW, 28.5 kg lighter | | [Easun Power IGRID-VX-IV-5.6KW-WIFI](https://comparepv.com/inverter/easun-power-igrid-vx-iv-5-6kw-wifi) | 5.6 kW | | 1 | 10.5 kg | -0.4 kW, 28.0 kg lighter | | [Easun Power ISOLAR-SMX-II-5.6KP-WIFI](https://comparepv.com/inverter/easun-power-isolar-smx-ii-5-6kp-wifi) | 5.6 kW | | 1 | 10.5 kg | -0.4 kW, 28.0 kg lighter | --- Source: https://comparepv.com/inverter/growatt-spf-6000t-dvm-g2
