Q: What is included in the 3.5kW MUST Hybrid Solar Kit?

A: The kit includes a 3.5kW MUST hybrid inverter, two 200Ah 12V lithium batteries, two 615W solar panels, solar cable, battery cable, mounting rails, a changeover switch and a DC breaker.

Q: What is the total solar-panel capacity?

A: The two 615W solar panels provide a combined solar capacity of 1,230W, equivalent to 1.23kW.

Q: What appliances can this solar kit power?

A: It can power compatible lighting systems, televisions, entertainment systems, refrigerators, Wi-Fi routers, CCTV systems, laptops, fans and small office equipment. The total connected load must remain within the inverter’s supported capacity.

Q: Can it power a refrigerator?

A: Yes. It can power a compatible refrigerator, provided its running wattage and compressor-starting surge remain within the inverter’s limits. Refrigeration will reduce the available battery-backup time.

Q: Can it power several appliances simultaneously?

A: Yes. The 3.5kW inverter can support several compatible appliances simultaneously, provided their combined running power and starting surges remain within the system’s capacity.

Q: How long can the batteries provide backup power?

A: Backup time depends on the connected appliances and their energy consumption. Lights, Wi-Fi, CCTV and laptops will generally run longer than refrigerators, televisions and other higher-consumption appliances. A load assessment provides the most accurate estimate.

Q: Can the system provide overnight backup?

A: Yes. It can provide overnight backup for carefully managed essential loads such as lights, Wi-Fi, CCTV, television and device charging. Actual runtime depends on battery charge and appliance usage.

Q: Can the solar panels power appliances while charging the batteries?

A: Yes. During sunny conditions, the solar panels can support connected appliances while charging the lithium batteries. Performance depends on sunlight intensity, battery charge level and the daytime load.

Q: Does the system automatically provide backup during a blackout?

A: The hybrid inverter manages power from the solar panels, batteries and utility grid. The included changeover equipment allows the system to provide battery backup when grid electricity is unavailable.

Q: Can the batteries also be charged using grid electricity?

A: Yes. The hybrid inverter can support charging from solar energy and utility-grid electricity, depending on its configuration and selected settings.

Q: What is the purpose of the changeover switch?

A: The changeover switch allows safe switching between available power sources and helps isolate different supply sources when required.

Q: What is the purpose of the DC breaker?

A: The DC breaker provides electrical protection and allows the solar circuit to be safely isolated during maintenance, inspection or an emergency.

Q: Is this system suitable for a home or apartment?

A: Yes. It is suitable for homes and apartments requiring dependable backup for lighting, entertainment, refrigeration, internet equipment and other compatible appliances.

Q: Is the system suitable for a shop or office?

A: Yes. It can support shops, offices and small businesses using compatible lights, computers, Wi-Fi equipment, CCTV systems, televisions and refrigeration appliances.

Q: Can it power an electric cooker, kettle, iron or water heater?

A: These appliances consume significant amounts of power and may discharge the batteries quickly. Their wattage and the other connected loads should be assessed before use.

Q: Can it power an air conditioner or water pump?

A: Compatibility depends on the appliance’s running wattage and motor-starting surge. A professional load assessment is recommended before connecting an air conditioner or water pump.

Q: What are the benefits of lithium batteries?

A: Lithium batteries offer faster charging, improved efficiency, dependable backup performance and lower routine maintenance compared with many conventional lead-acid batteries.

Q: Can I add more batteries or solar panels later?

A: The system is designed to be scalable. Additional compatible components may be added after confirming the inverter’s supported battery configuration, charging capacity and maximum solar-input limits.

Q: Are installation accessories included?

A: Yes. Solar cable, battery cable, mounting rails, a changeover switch and a DC breaker are included. Additional materials may be required depending on the roof type, cable distance and installation conditions.

Q: Does the system require regular maintenance?

A: The system requires minimal maintenance. Keep the solar panels clean, inspect cables and connections periodically, and install the inverter and batteries in a dry, secure and properly ventilated location.

Q: Will this system reduce my electricity bill?

A: Yes. It can reduce reliance on grid electricity by using solar energy during the day and stored battery energy during blackouts or low-sunlight periods. Actual savings depend on daily energy consumption and system settings.
