Frequently Asked Questions
What does “DC900V” capability mean for my application?
The DC900V rating (specific to 400V class models like 5R5G-4) means the inverter can accept high-voltage DC bus input directly, up to 900V DC. This is critical for solar-integrated industrial systems where PV arrays feed a DC bus directly, or for DC microgrid applications. It eliminates the need for additional DC-AC conversion stages, reducing system complexity and conversion losses. For standard AC grid applications, the inverter operates normally on three-phase 400V AC input, internally generating the DC bus.
Should I choose the G-type or P-type model for my 5.5kW application?
Select based on your load characteristics: G-type (General) provides 150% overload capacity for 60 seconds, designed for constant torque applications like CNC machines, conveyors, and compressors where full torque is needed at all speeds. P-type (Pump/Fan) provides 120% overload capacity, optimized for variable torque loads like centrifugal pumps and fans where torque requirements decrease at lower speeds. For CNC and textile machinery, choose G-type. For HVAC and pumping, P-type offers better energy optimization. The 7R5P-4 provides higher power (7.5kW) in a P-type configuration for larger pump applications.
Do I need an external braking resistor with the built-in brake unit?
The brake chopper is built-in, but the braking resistor is external. The 5.5kW models include an internal IGBT brake chopper circuit that manages regenerative energy during deceleration. You must connect an appropriately sized external braking resistor (typically 100-200Ω, 1-2kW rating for 5.5kW drives) to dissipate this energy as heat. Without the resistor, the drive cannot execute rapid stops or handle high-inertia loads. For standard pump and fan applications with long deceleration ramps, the resistor may be optional. Contact our technical team for resistor sizing based on your duty cycle and deceleration requirements.
Can this 5.5kW VFD replace my existing star-delta starter for energy savings?
Yes, with significant benefits. Replacing a star-delta starter with the 100PV VFD provides soft-start capability (eliminating mechanical shock and water hammer in pumps), variable speed control (optimizing flow/pressure rather than throttling), and 30-50% energy savings at partial loads compared to fixed-speed operation. The built-in brake unit also enables rapid stopping versus coast-to-stop with star-delta. For a 5.5kW motor running 8,000 hours/year at 75% load, typical payback is 12-18 months depending on local electricity rates. The RS485 interface also enables remote monitoring impossible with traditional starters.
