Frequently Asked Questions
How to choose a suitable inverter?
For resistive loads like bulbs, a modified wave inverter works. For inductive or capacitive loads (fans, AC, fridge, coffee machines), we recommend a pure sine wave inverter for better equipment longevity and performance.
How do I choose the size of the inverter?
Resistive loads can match the inverter power. For capacitive loads, choose 2-5 times the power. For inductive loads, choose 4-7 times the power to handle startup surges.
What is the best way to connect batteries to the inverter?
Keep cables as short as possible (ideally under 0.5M). Longer distances cause voltage drops, which may trigger under-voltage alarms. Always ensure correct polarity.
How to calculate the working hours for a specific battery configuration?
Use the formula: Work hours = Battery Capacity (AH) * Battery Voltage (V) * 0.8 / Load Power (W). Note: This is a reference value as battery condition affects actual results.
What are the advantages of the dual MPPT controller?
The built-in two 4000W MPPTs allow for a wider input range (120-450VDC) and better efficiency in harvesting solar energy from two different strings or orientations.
Does this inverter support parallel operation?
Yes, this model supports parallel operation for up to 6 units, allowing you to scale your power system as your energy needs grow.
