24V 48V Single Phase Off Grid Hybrid Solar Inverter Pure Sine Wave MPPT Detachable Dust Cover Harsh Environment
FAQs from Different Countries
1. Kenya
Q1: Is the EM1500 model sufficient for a small rural homestead with lights, a TV, and charging phones?
A: Perfectly. The 1.5KW/1500VA model is an ideal entry-level system for basic rural electrification, capable of powering LED lights, a small TV, radio, and phone chargers for several hours on a modest battery bank.
Q2: Can the MPPT handle the high-altitude, intense sunlight we experience?
A: The MPPT is designed to operate efficiently in high-irradiance conditions. The high PV voltage range (up to 500V) helps mitigate voltage drops over long wire runs, which is common in sprawling homesteads.
Q3: How reliable is the WiFi monitoring in areas with weak mobile signals?
A: The WiFi module connects to your local router. For areas with no internet, a local LAN connection can still be used. For remote monitoring, a cellular-based data solution would be required separately.
Q4: What is the difference between the SOL and SBU modes?
A: SOL (Solar First): Uses only solar and battery, never the grid. SBU (Solar, Battery, Utility): Uses solar first, then battery, and only switches to grid if battery is low. SBU is more flexible for locations with an unreliable grid.
Q5: If I only have a small budget for batteries now, can I still use the system?
A: Yes. You can start with a smaller, more affordable battery bank and use the "No Battery Mode" during the day. As your budget allows, you can easily expand your battery storage.
Q6: Do you offer training for local technicians on installation and maintenance?
A: Yes, we are committed to building local capacity. We periodically conduct training sessions for our partner technicians to ensure high-quality, standardized installations and service across the region.
2. South Africa
Q1: With load-shedding, can the inverter automatically switch back to grid when power returns?
A: Yes. The inverter automatically and continuously monitors the grid (Utility) supply. Once stable grid power is restored, it will seamlessly switch back to using it and begin recharging the batteries if configured to do so.
Q2: Is the efficiency high enough to make a real difference with our rising electricity costs?
A: With a peak efficiency of 96% from PV to AC, very little solar energy is wasted as heat. This high efficiency translates directly into lower energy bills and a faster return on your investment.
Q3: Can it be used as a UPS for a home office with a PC, printer, and internet router?
A: Absolutely. The pure sine wave and fast transfer time (10ms for PCs) make it an ideal backup power solution for home offices, ensuring your work continues uninterrupted during load-shedding.
Q4: What are the physical dimensions? Will it fit in a standard meter board cabinet?
A: The dimensions are compact. For example, the 3.5KW model is 358x295x100mm. It should fit in many standard cabinets, but we recommend checking the space and ensuring adequate ventilation as per the manual.
Q5: Are the products certified with South African National Standards (SANS)?
A: Our inverters are designed to meet international safety and EMC standards. We are actively engaged in the certification process with relevant South African bodies to ensure full local compliance.
Q6: Can I connect a generator directly to the AC input?
A: Yes, the AC input can be connected to a generator. The inverter will synchronize with the generator's output and can use it to charge the batteries, providing a comprehensive multi-source backup solution.
3. Egypt
Q1: How does the inverter perform in the extreme heat of the desert summer?
A: The operating temperature goes up to 50°C. For optimal performance and longevity in consistently high temperatures, we recommend installing the unit in a shaded, well-ventilated area to assist with heat dissipation.
Q2: Is the PV start voltage low enough to start generating power early in the morning?
A: Yes, the MPPT operates from as low as 60VDC, allowing it to begin harvesting solar energy early in the day when the sun is low, maximizing your daily energy production window.
Q3: Can this system power a submersible water pump for irrigation?
A: Yes, the high surge capability is excellent for starting pump motors. You can run a submersible pump directly from the inverter using solar or battery power, making it ideal for off-grid agriculture.
Q4: What is the dust protection level? Is it suitable for sandy environments?
A: The detachable dust cover provides significant protection against sand and dust ingress. For extremely sandy conditions, an additional external enclosure is recommended for maximum protection.
Q5: Does the BMS communication allow for detailed battery monitoring?
A: Yes, when connected to a compatible lithium battery via RS485, the inverter can read and display key data like State of Charge (SOC), voltage, and temperature, giving you full visibility of your battery's health.
Q6: Is technical documentation available in Arabic?
A: We provide user manuals and quick installation guides in multiple languages, including Arabic, to ensure our customers can install and operate the system with confidence.
