Welcome in 2013! The year of the solar and energy-storage revolution.

In 2013 we continue to help the worldwide community by means of the Solar Energy solutions: affordable , direct solar invertors, sine inverters and . Energy Storage: DC power solar cha

Micro-Inverter –  No Fear of Death

Micro-Inverter – No Fear of Death

Standard PV installations with work with DC 400V to DC 800V. Total risk of electric shock and death ! ! !

With Micro-Inverter working with DC 50V – 100% SAFETY- no risks of burns, shocks or deaths because of high DCa voltages

Micro-Inverter – No Fear of Fire

Standard PV installations have high risk of FIRE due to high voltage. DC 400V to DC 800V – extreme risk of FIRE. Bad contact, poor connection or some other fault may cause sparking and cable overheating. The total power of 3 kW to 5 kW is car

Question: What is the purpose of the eGate? Must I use it?

Question: What is the purpose of the eGate? Must I use it?

Answer:

1) For commercials installations when the energy is delivered to the public grid the eGate must be installed so that the installation meets the standards of the grid operators.

2) For small installations (only few MicroInverters)&n

FAQ: MicroInverter Questions and Answers

Question: Why do you recommend to use a 250Wp or even 280Wp solar panel with the MicroInverter, that has only 230W AC output power?

Answer: The solar panel specification (250Wp or 280Wp) is the peak power at the ideal condition of direct sunshine at 1000W/m2. On most installations this ideal condition will be pre

Micro-Inverter –  All Panels Supported

Micro-Inverter – All Panels Supported

All types of panels supported: MONO/POLY/Amorphous/Thin. All sizes of panels supported from 40Wp to 280Wp

With micro-inverters it is easily possible to reuse the “old” panels from other installations. The MicroInverters solve the “solar p

Micro-Inverter –  More Power from Eeast + West

Micro-Inverter – More Power from Eeast + West

Combining the EAST and WEST orieneted panels will give you more daily production than from south oriented panels only.

Yield more power with Micro-Invertors and solar panels on EAST and WEST located roofs: Get up to PLUS 38% power

Micro-Inverter –  Multiple Roof Orientation

Micro-Inverter – Multiple Roof Orientation

Solar panels can be installed on complicated roofs with different orientations. With Central inverter the installation of such roofs was not possible. With Micro-Inverters thepanels will generate maximum energy at any orientation and a
