    Multiple Working Modes
    5 What Size Inverter Should I Buy?
    • 1 Sizing the right power output. Inverters will be rated by a wattage value, telling you how many watts it can run at one time. For example, imagine you had a 500W Fridge and 800W Air Conditioning — these two items total 1300W and would require an inverter with a higher wattage than 1300W. (The calculation methods of variable frequency and fixed frequency are different.)
    • 2 Check your battery voltage. The DC voltage rating on the inverter will tell you what battery bank it is compatible with. For example, a 48V battery bank will require an inverter compatible with 48V DC input.
    • 3 Size your installation space. Make sure the inverter will fit in the space you have in mind with enough room around it for proper ventilation and no fire hazards.
    • 4 Need help? If you don't know much, we will provide you with one-stop service.
    How to Choose the Right Inverter Size
    ❓ Frequently Asked Questions (FAQ)
    Q What is the difference between the SST48HW3.5K, SST48HW5.5K, and SST48HW10K models?
    The three models differ primarily in rated output power (3500W, 5500W, and 10000W), maximum peak power (6000W, 10000W, and 15000W), MPPT charging current (60A, 100A, and 200A), and motor load capacity (2HP, 4HP, and 6HP). The 10KW model also features dual MPPT inputs (2×5500W PV arrays) and a larger physical size (130×445×630mm vs 130×350×455mm).
    Q What types of batteries are compatible with this solar off-grid inverter?
    This inverter supports Lithium batteries, Lead-acid batteries (including Sealed, AGM, Gel, and Flooded types), and User Defined battery settings. The rated battery voltage is 48V DC with a working voltage range of 40–60V DC.
    Q Can multiple inverters be connected in parallel for higher power output?
    Yes. This inverter supports parallel connection of up to 9 units, allowing you to significantly scale up your off-grid power system capacity to meet larger energy demands for commercial or industrial applications.
    Q What are the available charging modes and output modes?
    The inverter offers 4 charging modes: Only Solar, Mains Priority, Solar Priority, and Mains & Solar combined off-grid charging. For output, there are 2 modes available: Mains Bypass output and Inverter output. The system switching time between inverter and bypass is 10ms (typical), ensuring minimal disruption to connected loads.
    Q What communication interfaces does this inverter support?
    The inverter features multiple built-in communication interfaces including RS485, CAN, USB, and Dry Contact. It also supports external wireless modules including WIFI and GPRS, enabling remote monitoring and system management via smart devices or cloud platforms.
    Q What certifications does this solar inverter hold, and what are the protection features?
    This inverter is CE certified (IEC62109-1) for safety and complies with EN61000 for EMC standards. It provides comprehensive 360° protection including short circuit protection, over-voltage and under-voltage protection, overload protection (with tiered response: 102%–110% for 5 min, 110%–125% for 10s, >125% for 2s), reverse polarity protection, and charging short circuit protection via blown fuse.
