Technical Specifications & Expert Opinion
| Rated Power | 6200W / 6.2kVA |
| Surge Power | 12400VA |
| Waveform | Pure Sine Wave |
| Nominal Voltage | 220/230VAC ± 5% |
| Peak Efficiency | 93% (Battery Mode) |
Sona Solar Opinion: The 6200W continuous output is a significant step up from standard 5kW models, providing ample power for demanding households. The high surge capacity is excellent for motor-based loads, and the pure sine wave output ensures the safety of all sensitive electronics.
| Max PV Array Power | 6500W |
| MPPT Voltage Range | 60VDC – 500VDC |
| Max PV Open Circuit Voltage | 500VDC |
| Max Solar Input Current | 27A |
| Max Solar Charge Current | 120A |
Sona Solar Opinion: This is the standout feature. A 120A MPPT is exceptionally powerful, allowing you to connect a large solar panel array (up to 6.5kW) for rapid battery charging. The very wide voltage range (up to 500V) offers great flexibility in how panels are configured, which is a major advantage for complex roof layouts and maximizing solar harvest.
| Max AC Charge Current | 80A |
| Max Total Charge (PV+AC) | 120A |
| Nominal Battery Voltage | 48VDC |
| Lithium Communication | RS485 |
Sona Solar Opinion: The unit is designed for modern 48V battery systems and includes the essential RS485 communication port, making it fully compatible with high-quality LiFePO4 batteries from brands like Svolt, Dyness, and Must. The Lithium Activation feature is a crucial safety net, capable of waking a battery from a low-voltage sleep state.
| Dimensions (D x W x H) | 438 x 295 x 105 mm |
| Net Weight | 9 kg |
| Operating Temperature | -10°C to 50°C |
Sona Solar Opinion: For a 6.2kW inverter, the unit is remarkably compact and lightweight, simplifying installation. The detachable dust cover is a thoughtful addition for the Zimbabwean environment, helping to protect internal components and extend the inverter's lifespan.
Frequently Asked Questions
Is Growtech the same as Growatt?
No. Growatt is a larger, internationally-recognized manufacturer of solar inverters. Growtech is a different, more regional brand that sources generic Axpert-type inverters from China and is known for mixed reliability and poor local support.
Is Growtech a good brand?
Growtech offers strong specifications for its price, making it a good value proposition. However, as a newer brand in Zimbabwe sourcing generic hardware, its long-term reliability is still being established and is highly dependent on the quality of the initial installation.
What does error code [Bp] mean?
This is a battery error that can occur if the inverter suddenly loses communication with its batteries, particularly after a power trip.
Why is my inverter not charging the battery?
- Check for a blown fuse or a tripped circuit breaker.
- Verify that the battery terminals are not loose.
- If using wet-cell batteries, ensure the electrolyte level is not dry.
Why is my inverter overheating?
- Ensure the inverter is in a well-ventilated area with proper clearance.
- Check that the cooling fans are not blocked by dust or debris.
- Reduce the load on the inverter if it is running too hot.
How do I get technical support?
Official support for the Growtech brand can be limited. Therefore, it is critical to purchase from a reputable installer like Sona Solar Zimbabwe, as we handle all technical support and warranty claims directly.
How do I make a warranty claim?
Your warranty is held with the local distributor or installer you bought the product from. The process and reliability of claims can vary significantly, which is why choosing an established company is vital.
Can this inverter run an oven or large air conditioner?
No. While powerful, this inverter is not designed for the sustained high demand of heat-generating appliances. An oven or large AC unit requires a specialized, industrial-grade system (typically 10kVA or larger) with a massive battery bank.
What size battery is best for this inverter?
To match its high power output, we recommend a minimum of 5kWh (e.g., 1 x 48V 100Ah) of lithium battery storage. For those looking to maximize its off-grid potential and run heavy loads like pumps for longer, a 10kWh battery bank (2 x 48V 100Ah) would be the ideal pairing.
Ready to Power Everything?
The Growtech Axpert 6.2kW inverter is an excellent, high-performance choice for larger homes and businesses needing to power more than just the basics. Its reliability, however, hinges on a professional installation and a correctly sized system. Trust the experts at Sona Solar Zimbabwe to design a complete package that unlocks this inverter's full potential.
