Which Growatt Inverter is Right for You?
SPF 3500 ES (3.5kVA)
The ideal off-grid inverter for small to medium homes. Powers lights, a fridge, TV, Wi-Fi, and essential appliances with ease — ensuring consistent performance during load-shedding.
SPF 5000 ES (5kVA)
A strong, all-round off-grid inverter for larger homes. Handles daily household needs plus demanding loads like borehole and booster pumps with high surge capacity (2x rated power).
MIN-XH Series (Hybrid)
Growatt’s new-generation hybrid inverter — designed for smart grid-tied homes. Supports solar panels and battery storage for reliable, efficient backup and intelligent power management.
MAX Series (Commercial)
Built for large-scale solar and business operations. Offers high efficiency, modular scalability, and intelligent monitoring — delivering strong performance for commercial and industrial systems.
In-Depth Technical Specifications (SPF ES Series)
Sona Solar Opinion: Growatt's SPF ES series offers impressive continuous power. A key feature is the high surge capacity—2x the rated power for 5 seconds. This is excellent for handling the high startup current of motors in borehole pumps and fridges. The pure sine wave output is critical for the safety of sensitive electronics.
| Specification | SPF 3500 ES | SPF 5000 ES |
|---|---|---|
| Rated Output Power | 3.5kVA / 3.5kW | 5kVA / 5kW |
| Surge Capacity | 2* rated power for 5 seconds | 2* rated power for 5 seconds |
| Output Voltage Waveform | Pure Sine Wave | |
| Peak Efficiency | 93% | |
Sona Solar Opinion: This is a major strength. The SPF 5000 ES features a powerful 100A MPPT solar charge controller, allowing for a solar array of up to 6,000W. This is crucial for rapidly recharging batteries and powering heavy loads directly from the sun. The wide MPPT voltage range gives our installers great flexibility in designing the most efficient panel configuration.
| Specification | SPF 3500 ES | SPF 5000 ES |
|---|---|---|
| Max. PV Array Power | 4500W | 6000W |
| Max. PV Array Open Circuit Voltage | 450Vdc | |
| PV Array MPPT Voltage Range | 120Vdc ~ 430Vdc | |
| Max. PV Charging Current | 80A | 100A |
Sona Solar Opinion: The SPF ES series includes the essential CAN/RS485 communication port. This is a non-negotiable feature that allows the inverter to "talk" to the Battery Management System (BMS) of high-quality lithium (LiFePO4) batteries. This intelligent communication is vital for optimizing battery performance, ensuring safety, and maximizing the lifespan of your battery bank.
| Specification | SPF 3500 ES | SPF 5000 ES |
|---|---|---|
| Nominal DC Input Voltage | 48Vdc | |
| Max. AC Charging Current | 60A | 80A |
| Total Max. Charging Current (AC + Solar) | 80A | 100A |
| BMS Communication | CAN / RS485 | |
Frequently Asked Questions
Yes, Growatt is an excellent choice. It offers premium specifications for its price point, making it a strong contender in the value-for-power segment. Its powerful MPPT chargers and robust design make it very capable for Zimbabwean conditions. As with any inverter, its long-term reliability is heavily dependent on a high-quality, professional installation.
To match the high power output of the SPF 5000 ES model, we recommend a minimum of 5kWh of lithium battery storage (e.g., 1 x 48V 100Ah). For users who want to maximize their off-grid capability and run heavy loads, a 10kWh battery bank (2 x 48V 100Ah) would be the ideal starting point.
The manufacturer's warranty is strictly conditional upon the unit being installed by a qualified electrician who issues a Certificate of Compliance (COC). This ensures the system is wired correctly, earthed, and has the necessary safety protections. An incorrect installation can damage the inverter, void the warranty, and poses a significant safety risk.

The Growatt inverter series offers a high-performance, intelligent choice for homes and businesses. 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.
