Clean power for Devialet

[chrisc]

Tried several power conditioners.  The drawbacks (mainly loss of dynamics) outweigh the benefits.  

What does work however, is a pure sine wave inverter attached to PV panels and batteries.   Rock solid 230 VAC with no trace of noise, as viewed on an oscilloscope display

That's an interesting observation. Could you give us more info on that? I'm planning for solar panels and batteries on my roof myself.

In 2015 we had several months of "load shedding".   Being without electricity at night is pain in the rear end after a few mins, so I installed...

8 x 300 watt PV panels
An 8 amp pure Sine Wave inverter which I bought from MPP Solar in Taiwan
4 x 105 a/h batteries each giving 24 VDC
A separate earth-leakage circuit-breaker
Other circuit-breakers, for safety purposes

The inverter charges the batteries and in sunlight, provides 230V electricity.  At sunset, it switches over to the incoming mains.  If the incoming mains is absent, it uses the batteries.   This is all done automatically.   You can set parameters for voltages, load, etc

In summer (October to April) the PV panels provide power for 12 - 14 hours a day.  Even now, which is at the end of winter, there are about 15 sunny days a month.  I live in Cape Town in South Africa, 34 deg south

This lot was attached to all the house lights and 3 plug circuits
