Micro-Inverter –  No Fear of Winter

Micro-Inverter – No Fear of Winter

For normal installation the snow cover on part of the panels will decrease the performance of all solar panels.

With Micro-Inverter the performance of panels will be always maximized. The MicroInverters will give more energy yield from panels part

Micro-Inverter – No Fear of Shading

Micro-Inverter – No Fear of Shading

With tranditional PV installation there is huge loss of energy yield caused by partial or full shading. The shading of just part of the panels is a BIG PROBLEM !

Micro-Inverter solution gives more power when panels are fully or partially shaded. There i

Micro-Inverter – Always Stable System

Micro-Inverter – Always Stable System

The serial strings of PV panels with one central inverter bring many problems… if one panel is weak… …the whole systems is weak if one panel is broken… …the whole system must be stopped

Micro-Inverter – More Power from the Sun

Micro-Inverter – More Power from the Sun

Ordinary solar installation with central inverter works with serial strings of many panels. The total power is based on the performance of the whole string. There is only 1x MPPT (maximal power point tracking) for the whole string. If the performance

Home Electric Energy Storage Project

We are now working on a testing installation of a Home Electric Energy Storage (HEES) Project with 5kWh battery bank and 1kW power to grid. We will keep you informed about the project at the blog pages.

The Micro-Inverter Safety and Operation FAQs

The Micro-Inverter Safety and Operation FAQs

Q: Can the Micro-Inverter work in off-grid mode (island mode)?

Answer: No. The Micro-Inverter is designed only as the grid-tied (or on-grid) inverter. It works simultaneously (in harmony) with the 230V AC grid.

Q: How will the Micro-Inverter beha

The graphs show the energy consumption and energy self-generation. The green line is the energy taken from the grid. The blue line is the self-produced energy. The more energy is produced, the less energy needs to be taken from the grid.

Micro-Inverter allows simple energy management

Standard PV invertors do not allow any power regulation. These inverters are ALWAYS feeding the grid with ALL the energy they receive from the panels. No way to regulate the output power.

Micro-Inverter installation allows the energy management with simple AC relay switch-box. Based on the energy de

Micro-Inverter is MICRO! Good ideas for you

With Micro-Inverter it is easy to make even very small installations. You can have a solar project with just ONE solar panel. This is not possible with the ordinary central inverters that usually have 1.5 kW or more power.

Now you can start from just o
