- Global leader with proven R&D.
- Superior smart monitoring (ShinePhone app).
- High-efficiency, often silent operation.
- Comprehensive product ecosystem.
- Excellent power output for the price.
- Powerful MPPT charge controllers.
- Robust features for off-grid use.
- Great for handling motor-based loads.
Head-to-Head Comparison
Growatt: A top-tier, global leader established in 2010. They are a massive company with a huge investment in R&D, a presence in over 100 countries, and are one of the world's most popular inverter suppliers. Their brand is synonymous with innovation and reliability.
Growtech: A brand known for producing robust, feature-packed off-grid hybrid inverters, such as the Axpert series. It is a strong player in the high-value segment, often seen as a rebranded or specialized line of inverters focused on powerful off-grid performance rather than a global corporate brand like Growatt.
Growatt: Their key differentiator is their smart ecosystem. The ShinePhone app is best-in-class for remote monitoring. Their inverters, like the SPF ES, feature high-efficiency MPPT chargers, while others, like the SPF HVP, use reliable PWM technology for cost-effectiveness. Many models boast a sleek, fanless design for silent operation.
Growtech: Their primary strength is raw power and off-grid functionality. Models like the Axpert 6.2kW feature extremely powerful 120A MPPT solar chargers and a high PV input voltage range (up to 500Vdc), making them excellent for large solar arrays. They also include features like lithium battery activation and a detachable dust cover, designed for harsh environments.
Growatt is for: The tech-savvy homeowner who values data, smart control, and a sleek aesthetic. It's for users who want a complete, intelligent energy management system from a globally trusted brand with a strong warranty.
Growtech is for: The user who needs maximum off-grid power and durability for the price. It's ideal for larger homes with demanding loads like borehole pumps or for users in harsh environments who prioritize robust performance over a sophisticated app ecosystem.
Technical Deep Dive
The Growatt SPF ES Series is a next-generation off-grid inverter designed for reliability, efficiency, and user flexibility. It combines a powerful pure sine wave inverter, an MPPT solar charge controller, and an AC charger into one compact unit. With power ratings from 3kVA to 6kVA, it is ideal for home and small commercial solar systems.
This series supports a wide PV input voltage range (120V–450V DC) and integrates a high-efficiency MPPT charge controller that ensures maximum solar harvest under varying sunlight conditions. Its dual AC input allows automatic switching between utility and generator power sources. The SPF ES series also features programmable battery charging for lithium, AGM, or gel batteries, enabling full customization to meet your specific energy needs.
Advanced connectivity options such as WiFi or GPRS modules make remote monitoring and system diagnostics easy via the Growatt ShinePhone App. With intelligent protection against overload, short circuit, and battery over-discharge, the SPF ES delivers dependable performance for homes experiencing frequent load-shedding.
The Growatt SPF HVP Series represents a premium upgrade for high-voltage solar systems requiring greater efficiency and scalability. Designed for both off-grid and hybrid applications, it supports larger PV arrays and faster battery charging, making it perfect for mid-size households, farms, and small businesses.
With PV input voltages up to 500V and a maximum efficiency above 98%, the HVP series maximizes solar utilization while reducing energy loss. It includes a dual MPPT tracking system for superior performance under partial shading and diverse roof orientations. The inverter’s built-in communication ports (RS485, USB, and WiFi) make integration with smart energy management systems seamless.
Its robust design features active cooling, anti-dust protection, and wide temperature tolerance, ensuring stable performance in Zimbabwe’s challenging climate. The HVP Series also supports parallel operation, allowing up to 6 units to work together for larger installations, providing scalable energy independence.
The Growtech Axpert Series is a versatile inverter range engineered to balance affordability and performance. Known for its robust build and high conversion efficiency, the Axpert series serves as a reliable off-grid inverter option for households and SMEs seeking cost-effective power backup.
Available in 1kVA to 5kVA configurations, the Axpert series integrates a high-efficiency PWM or MPPT charge controller (depending on the model) and supports both lead-acid and lithium batteries. Its intelligent CPU control system ensures optimized battery charging, system protection, and smooth switchover between grid and inverter modes.
The Axpert’s compact design, easy installation process, and user-friendly LCD interface make it ideal for home users seeking dependable off-grid power. Though it lacks some advanced hybrid features found in Codi or Growatt’s latest models, the Growtech Axpert remains one of the most durable and proven solutions in Zimbabwe’s solar market — offering unmatched reliability at an attractive price point.
The Final Step: Choosing an Authorized Distributor
Regardless of which inverter brand you choose, purchasing from an authorized distributor is critical. It ensures that you receive a genuine product covered by the official manufacturer’s warranty, along with reliable technical support and access to the latest firmware updates. Unauthorized purchases may save money upfront but often lead to poor after-sales support, compatibility issues, and a shorter system lifespan.
