Frequently Asked Questions
- The Crown Xavier 4kW delivers 4000W on a 24V battery while the 6kW delivers 6000W on a 48V battery. This is an important distinction — the 6kW operates at a higher voltage which is more efficient for larger loads. The 6kW also supports 9000W of solar input versus 6000W for the 4kW. Both have 120A MPPT chargers, dual output, built-in BMS and Wi-Fi. Choose the 4kW for homes with total backup loads under 3500W (fans, lights, TV, small AC). Choose the 6kW if you run a 1 ton or larger AC as part of your backup load — the 48V system handles it more efficiently.
- Yes, the Crown Xavier 4kW can technically run a 1 ton inverter AC (900W startup, 700W running), but with limited headroom. With the AC running at 900W plus refrigerator (150W), fans (150W) and lights (50W), total load reaches 1250W — within the 4000W capacity. However, for a home planning to run an AC during load shedding, the 6kW at Rs 120,000 is recommended for more comfortable headroom. The 4kW is best suited for homes where the AC is NOT part of the backup load and backup is primarily for fans, lights and small electronics.
- The Crown Xavier 4kW at Rs 108,000 significantly outperforms basic inverters in the same price range. Key advantages: pure sine wave output (safe for all electronics including inverter ACs) versus modified sine wave in cheaper alternatives; built-in 120A MPPT solar charger (most basic inverters have no or low-quality MPPT); built-in BMS for lithium battery support; built-in Wi-Fi for remote monitoring; dual output for smart load management; and 6000W solar input capacity versus 1000-2000W in basic alternatives. At Rs 108,000, it is exceptional value from a trusted local brand with 4-year warranty.
- Yes, the Crown Xavier 4kW is fully compatible with 24V LiFePO4 and lithium-ion batteries through its integrated BMS. The built-in BMS communicates with the battery management system via CAN or RS-485 for safe, optimised charging. Compatible 24V lithium batteries include Crown own 24V lithium range and other standard 24V LiFePO4 batteries. For best performance, a 24V 200Ah LiFePO4 battery (4.8kWh) paired with the Xavier 4kW provides approximately 4-5 hours of full home backup excluding AC, or 2-3 hours including 1 ton AC.
- The Crown Xavier 4kW comes with a 4-year manufacturer warranty from Crown Micro Global. As a Pakistani brand, Crown Micro provides local after-sales support with nationwide service centres, making warranty claims significantly faster than imported brands. At MartOnline, all Crown products are sourced from authorised supply channels ensuring genuine warranty coverage.
