+263 78 922 2847Hanchu 3.5kW 24V Hybrid Inverter – Features, Specs & Expert Review
At Sona Solar Zimbabwe, we are proud to introduce the Hanchu 3.5kW 24V Hybrid Inverter (Model: HESS-OF-E-3.5K), a versatile and powerful solution designed for optimal performance and adaptability in the Zimbabwean context.
Key Features & Benefits
The inverter's Pure Sine Wave output and a power factor of 1.0 ensure a clean and stable power supply, which is essential for protecting sensitive electronics like TVs, laptops, fridges, and decoders from damage.
With a maximum PV input of 500VDC and a powerful built-in 100A MPPT solar charge controller, this inverter maximizes the energy harvested from your solar panels, ensuring faster battery charging and more efficient use of sunlight.
A crucial feature for flexibility, this inverter is capable of powering your loads directly from the solar panels during the day, even without a battery connected. This allows you to start your solar journey with panels and an inverter, and add batteries later.
It includes a detachable dust cover for the fan, providing extra protection against dust and ensuring longevity in the often harsh Zimbabwean environment.
An integrated EQ (Equalization) function helps to optimize battery performance and extend its lifespan by preventing sulfation on lead-acid batteries and balancing cells in lithium batteries, protecting your valuable energy storage investment.

Sona Solar Expert Opinion & FAQs
The Hanchu 3.5kW 24V inverter (HESS-OF-E-3.5K) is an impressive and highly competitive unit in the Zimbabwean market. Its standout feature is the powerful 100A MPPT controller combined with a high 500VDC PV input. This allows for greater flexibility in solar panel array design and ensures you capture the maximum possible power from the sun—a significant advantage for rapid battery charging and daytime power usage.
The "no battery" mode and detachable dust cover are thoughtful additions that demonstrate its suitability for local conditions. For its price point, it offers a set of features usually found in more expensive models. We highly recommend it for small to medium-sized homes looking for a reliable, efficient, and future-proof inverter to anchor their 24V solar system.
Yes. The Hanchu HESS-OF-E-3.5K can operate without a battery, offering flexibility for setups where battery storage is not required or will be added later.
- Check voltage: Ensure the solar panel voltage is within the inverter's range. Maximum PV input: 500VDC.
- Wire panels: Series panels for higher voltage within the MPPT range, then parallel strings.
- Set charging priority: Choose charging source (SOL for solar, UTL for grid) in the inverter menu.
- Check charge status: Verify 'CHG' indicator light flashes. If off, PV input may be too low to start charging.
- Overload: Exceeding 3.5kW rated capacity triggers automatic shutdown. Surge capacity: 7000VA.
- Incorrect settings: Wrong parameters can cause issues; resetting to defaults may help.
- External interference: AC leakage or unbalanced load may cause instability. Check installation with a qualified installer.
- Faulty wiring: Damaged or incorrect wiring can lead to low or unstable output.
Compatible with 24V batteries. Supports advanced integration with LiFePO₄ (lithium iron phosphate) batteries via RS485 communication. The EQ function optimizes lead-acid battery performance.
Contact your retailer or distributor for warranty registration and technical support. Hanchu provides official channels for documentation and software updates through web portals or apps.
