Common Questions Answered by Different Countries/Regions
1. Philippines
Maria Santos, Philippines Renewable Energy Journal
Can the system withstand salty and humid coastal conditions?
Yes, the casing is corrosion-resistant and designed for high humidity (5-95% non-condensing).
How does it perform during long rainy seasons with low solar yield?
It can charge from AC grid when solar is insufficient, with configurable priority modes (UTL, SOL, SBU, SUB).
Is installation technical support available locally?
Yes, we provide installation guides, video tutorials, and partner with local distributors for training.
Can it power a typical Filipino household with refrigerator, fans, and lights?
Yes, models from 2.5KW upwards can support basic home loads, with surge capacity for motor starts.
What battery type is recommended for tropical climates?
LiFePO4 is recommended for longer life and better performance in heat compared to lead-acid.
2. Vietnam
Nguyen Lan, Vietnam Energy Press
What is the price range for the EM series?
Pricing varies by model and distributor. We focus on high value with features like MPPT, lithium compatibility, and no-battery operation.
Can it be used in three-phase systems?
This is a single-phase inverter. For three-phase, multiple units can be configured with external synchronization.
How user-friendly is the interface for non-technical users?
Simple LED indicators, optional WiFi app, and clear labeling make operation intuitive.
What is the payback period for a typical solar system using this inverter?
Depending on local electricity rates and solar conditions, typically 3-5 years with reduced grid dependence.
Does it support Vietnamese-language monitoring software?
The mobile app supports multiple languages, including Vietnamese.
3. Saudi Arabia
Ahmed Al-Farsi, Saudi Solar Vision
How does it perform in desert temperatures above 50°C?
Operating range is up to 50°C. For hotter areas, we recommend shaded installation and adequate ventilation.
Can it integrate with diesel generators?
Yes, AC input accepts generator power. It can prioritize solar and battery to reduce generator runtime.
What is the dust protection level?
The detachable dust cover protects internal components, suitable for sandy environments.
Is there support for large PV arrays with high voltage?
PV input supports up to 500V DC, ideal for long string configurations in high-irradiation regions.
Can it be monitored remotely for off-grid sites?
Yes, with optional WiFi or cellular gateway, remote monitoring and management are possible.
