What Size Inverter Should I Buy?
- Size the right power output. Inverters are rated by a wattage value, telling you how many watts it can run at one time. For example, a 500W fridge and 800W air conditioning together equal 1300W and would require an inverter rated above 1300W. (Note: calculation methods differ for variable frequency and fixed frequency loads.)
- Check your battery voltage. The DC voltage rating on the inverter tells you what battery bank it is compatible with. For example, a 12V battery bank requires an inverter compatible with 12V DC input.
- Size your installation space. Ensure the inverter fits in your intended space with sufficient room around it for proper ventilation and no fire hazards.

❓ Frequently Asked Questions (FAQ)
💬 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, 15000W), MPPT charging current (60A, 100A, 200A), and the number of MPPT inputs (1 for 3.5K and 5.5K; 2 for 10K). The 10K model also supports a higher bypass overload current of 63A.
💬 What battery types are compatible with this solar off-grid inverter?
This inverter supports Lithium batteries, Lead-Acid batteries (including Sealed, AGM, Gel, and Flooded types), as well as a User Defined option, making it highly flexible for various off-grid energy storage setups.
💬 How many units can be connected in parallel?
Up to 9 units can be connected in parallel, allowing you to significantly scale up your off-grid power system capacity to meet larger energy demands for commercial or industrial applications.
💬 What are the available charging modes for this inverter?
The inverter supports 4 charging modes: Only Solar, Mains Priority, Solar Priority, and Mains & Solar off-grid charging. It also offers 2 output modes: mains bypass and inverter output, providing flexible energy management for different usage scenarios.
💬 What protection features does this inverter include?
The inverter features comprehensive 360° all-round protection, including short circuit protection, over-voltage and under-voltage protection, overload protection, reverse polarity protection, and charging short circuit protection via blown fuse. Overload protection activates at 102%–125%+ of rated load.
💬 Is this inverter suitable for outdoor or harsh environments?
The inverter carries an IP20 waterproof rating and operates within a temperature range of -10°C to 55°C, with a storage range of -25°C to 60°C. It uses forced air cooling with a variable-speed fan and produces less than 60dB of noise. While suitable for challenging environments, it is recommended for sheltered indoor or covered outdoor installations.
