Must Energy: Expert FAQs
Sona Solar engineers answer the most common questions regarding the daily operation and maintenance of MUST hardware in Zimbabwe.
A continuous or rhythmic beep is the inverter's internal alarm system speaking to you. The most common reasons are an Overload (you turned on a kettle or iron that exceeded the inverter's rated wattage), Low Battery Voltage (the battery is nearly empty during a long power cut), or Overheating (the cooling fans are blocked). Always ensure your inverter is installed in a well-ventilated area, and immediately reduce the appliance load if it begins to beep.
Yes, but this applies specifically to the higher-end High-Voltage models (like the 5.2kVA and 6.2kVA units). These models feature a massive PV input voltage capacity, allowing them to bypass the battery entirely and funnel pure solar energy directly to your home's circuitry. However, Sona Solar highly recommends installing at least one lithium battery to act as a buffer. If a heavy cloud suddenly covers the sun while you have no battery connected, the inverter will instantly shut down, causing your electronics to turn off abruptly.
Yes. While MUST batteries are specifically optimized to pair flawlessly with MUST inverters, their advanced internal Battery Management System (BMS) protocols are highly adaptable. They can successfully communicate with several other leading tier-1 inverter brands. However, you should always consult a Sona Solar engineer before attempting a mixed-brand installation to ensure the communication cables are pinned correctly for optimal safety.
The beauty of MUST LiFePO4 batteries is that they are entirely sealed and require absolute zero user maintenance. You never need to add distilled water or check acid levels. To ensure a multi-decade lifespan, the only requirement is to avoid chronically draining them to 0%. Sona Solar engineers will program your inverter to shut off automatically at a 15-20% reserve threshold, safeguarding the battery cells completely autonomously.
