The YC500 - dual microinveter

The YC500 is a dual micro-inverter with two MPPT units for higher yield of solar energy. See the comparison of the real yield using two different configurations.

One configuration is with 2x 260Wp panels, the other is with 2x 300Wp panels.

When using

Micro-inverters: More Energy From Shaded Panels

Some roofs may have a partial shading - prom chimneys, from parts of tries. With central inverter such partial shading will completely degrade the performance of the whole solar installation. With microinverters the shading is limited o

The table gives details about the possible Error Status reported by the microinverter.

Note: since microinverter issues are often“site-specific” (the problem cannot be simulated easily at a different location or installation)

A nice photo from a GridFree installation —- BUT WITH A PROBLEM!

A customer sent a photo from his first solar GridFree installation. This idea is easy: simply putting the solar panels on the flat roof of the house.

However looking at details of this installation, the installation will not work effectively. See the explanation:

FAQ: Monitoring the solar panels with microinverters

FAQ: Monitoring the solar panels with microinverters

Question: I have a small installation with just a few solar panels and microinverters. Is there some easy way to monitor this installation without the need to use some external monitoring system (like SEDAS or other)?

Answer: There
