Product Description:

1. Structure of Photovoltaic Grid-Connected Inverter SG40KTL Description

A solar inverter, or PV inverter, or Solar converter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into

 autility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network.

It is acritical BOS–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment.

Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.

Suitable for 50Hz/60Hz grid, could be used in Asia, Africa and Europe. Available for hand installation, no need for lifting machinery

 assistance.

 

2. Main Features of the Photovoltaic Grid-Connected Inverter SG40KTL

• Full 36kW effective power at power factor of 0.9 due to apparent power reserves up to 39.8kVA

• Max. Efficiency at 98.3%

• Dual MPP trackers control

• Reduced cabling on AC side due to higher output voltage of 480Vac

• Integrated combiner box: 8 x MC4 connector pairs with DC string fuses, Type II overvoltage protection and DC switch, more safety and lower the system cost

• Can be wall-mounted without lifting equipment, weight 65 kg

• Active power continuously adjustable (0~100%)

• Reactive power control with power factor 0.8 overexcited ~ 0.8 underexcited

• Includes RS-485 interface, compatible with all common monitoring systems

• Product certification: TÜV, BDEW and CGC

• Manufacturer certification: ISO 9001, ISO 14001, OHSAS 18000

5. FAQ of Photovoltaic Grid-Connected Inverter SG40KTL

Q1. What is the difference between inverter and solar inverter?

    A1. Inverter only has AC inpput, but solar inverter both connect to AC input and solar panel, it saves more power.

Q2. What is the difference between MPPT&PWM?

    A2. MPPT has higher efficiency, it can track the max power point and won't waste energy.
