More Energy

Traditional Inverter	SolarEdge Solution
MPPT per entire string - all modules receive the same current, regardless of their individual MPP	MPPT per module - current & voltage adjusted per module
Weak modules reduce the performance of all modules in the string or are bypassed	Maximum power from each module individually
Power losses due to module mismatch	2%-25% more energy from the PV system

 

   Cost Saving Maintenance

  Module-level performance monitoring & remote maintenance lead to:

• Less trips to site

• Less time spent on site

• Higher system uptime

  Free module-level monitoring for system lifetime

  Real-time full insight to system from anywhere

• Easy access via web browser and mobile device

 

   Future Compatibility & Warranty

• Low-cost inverter replacement out of warranty

• 40% less than traditional inverters

• SolarEdge flexible design allows modules of different power classes and brands in the same string

• No need for expensive module inventory stocking

• 25-year power optimizer warranty, 12-year inverter warranty, lifetime free monitoring

  Enhanced Safety

• No high VDC during installation or maintenance - power optimizers and DC cables automatically de-energize when inverter is disconnected or grid power is shut down

• Remote monitoring instead of diagnostics work at dangerous heights

• Only inverter certified to IEC 60947 as a disconnection means and to VDE 2100-712

• Better suited for future insurance requirements

 

 

  Motor Soft Starter

Soft starters can be set up to the requirements of the individual application.

A motor soft starter is a device used with AC electrical motors to temporarily reduce the load and torque in the power train and electric current surge of the motor during start-up. This reduces the mechanical stress on the motor and shaft, as well as the electrodynamic stresses on the attached power cables and electrical distribution network, extending the lifespan of the system.

It can consist of mechanical or electrical devices. Electrical soft starters can be any control system that reduces the torque by temporarily reducing the voltage or current input, or a device that temporarily alters how the motor is connected in the electric circuit.

Across-the line starting of induction motors is accompanied by inrush currents up to 7 times higher than running current, and starting torque up to 3 times higher than running torque. The increased torque results in sudden mechanical stress on the machine which leads to a reduced service life. Moreover, the high inrush current stresses the power supply, which may lead to voltage dips. As a result, lifespan of sensitive equipment may be reduced.

A soft starter eliminates the undesired side effects. Several types based on control of the supply voltage were developed. An overview of the various electric start-up types viz.

High currents and current peaks lead to high fixed costs charged by the power supply companies and to increased mains and generator loads.

A soft starter continuously controls the three-phase motor’s voltage supply during the start-up phase. This way, the motor is adjusted to the machine’s load behavior. Mechanical operating equipment is accelerated smoothly. This lengthens service life, improves operating behaviour, and smooths work flows. Electrical soft starters can use solid state devices to control the current flow and therefore the voltage applied to the motor.

In pump applications, a soft start can avoid pressure surges. Conveyor belt systems can be smoothly started, avoiding jerk and stress on drive components. Fans or other systems with belt drives can be started slowly to avoid belt slipping. Soft starts are seen in electrical R/C helicopters, and allow the rotor blades to spool-up in a smooth, controlled manner rather than a sudden surge. In all systems, a soft start limits the inrush current and so improves stability of the power supply and reduces transient voltage drops that may affect other loads.
