Short Description

The Growatt SPF 3000TL HVM-48 is a 3kW/3kVA, 48V pure sine wave hybrid inverter designed for solar, battery and utility/generator applications. It features a built-in MPPT solar charge controller, configurable energy-source priority, battery charging, LCD monitoring and protection functions. The unit supports both lithium and lead-acid batteries and is suitable for residential, office, small-business and backup-power applications. 

Product Description

The Growatt SPF 3000TL HVM-48 Hybrid Inverter combines inverter, battery charger and solar MPPT controller functions in a single compact unit.

With a 3,000W continuous rated output, 48V battery architecture and pure sine wave AC output, it can supply power to a wide range of household and professional electrical loads. Its built-in MPPT controller allows solar energy to be used for battery charging and load supply, while the AC input can be connected to utility power or a suitable generator.

The inverter is particularly suitable for customers looking to build a 48V solar backup system without purchasing a separate solar charge controller.

The manufacturer specifies a 60–115V DC MPPT operating range, 145V maximum PV open-circuit voltage, and up to 1,800W recommended PV array power for this model.

Recommended Solar Configuration

For this inverter, the PV design must respect the 60–115V MPPT operating range and 145V maximum open-circuit voltage. 

For example, when using conventional ~40–50V Voc solar modules, two suitable panels in series may be appropriate, provided the combined Voc remains safely below 145V under the lowest expected temperature.

Do not design the PV string based solely on panel wattage. Check:

Panel Voc

Panel Vmp

Panel Isc

Panel Imp

Temperature coefficient

Inverter MPPT range

Maximum PV Voc

Maximum allowable PV power

This is particularly important for professional installations.

Suitable Battery Options

Because this is a 48V inverter, suitable configurations include:

Lithium Battery

51.2V LiFePO₄ battery, for example:

5kWh 51.2V battery

10kWh 51.2V battery

15kWh 51.2V battery

Lead-Acid Battery

A 48V bank can be constructed using:

4 × 12V batteries in series

For example:

4 × 200Ah 12V batteries = 48V 200Ah

Nominal battery energy:

48V × 200Ah = 9.6kWh

Actual usable energy depends on battery chemistry and allowable depth of discharge.

Ideal Applications

The Growatt SPF 3000TL HVM-48 can be used for:

Homes

Offices

Shops

Small businesses

CCTV systems

Networking equipment

Lighting systems

Fans

Refrigerators

TVs

Computers

Solar backup systems

Small workshops

Rural/off-grid installations

For motor-driven appliances such as pumps, compressors and refrigerators, the starting/surge requirement must be checked before selecting the inverter.

Frequently Asked Questions

1. What is the capacity of the Growatt SPF 3000TL HVM-48?

It has a rated output of 3,000W / 3,000VA.

2. Is it a 48V inverter?

Yes. The inverter uses a 48V DC battery bank. 

3. Is the output pure sine wave?

Yes. It provides a pure sine wave AC output, making it suitable for many sensitive electronic and household loads. 

4. Does it have an MPPT charge controller?

Yes. The SPF 3000TL HVM-48 has an integrated MPPT solar charge controller.

5. What is the MPPT voltage range?

The specified MPPT operating range is 60–115V DC. 

6. What is the maximum PV voltage?

The maximum solar array open-circuit voltage is 145V DC. The PV array should never be designed to exceed this limit. 

7. How many solar panels can I connect?

The number depends on the panel Voc, Vmp and wattage. Panels must be configured so that the operating voltage remains within the MPPT range and the cold-weather Voc stays below 145V.

8. Can it work without solar panels?

Yes. It can operate from the battery and can also use an AC source such as utility power or a suitable generator, depending on the configured operating mode.

9. Can I use lithium batteries?

Yes. The published specifications list compatibility with lithium and lead-acid batteries. 

10. Can it run a refrigerator?

Yes, provided the refrigerator's running and starting/surge requirements are within the inverter's capabilities.

11. Can it charge the battery from the grid or generator?

Yes. It includes an AC charging function for battery charging from an AC source. 

12. Can this inverter be used for a complete home solar system?

Yes. It can form the core of a 48V solar backup system. The correct combination of PV array, battery capacity, protection devices, cables and load profile should be calculated before installation.
