Repairing an off-grid wind and solar electrical system

Low Impact

We recently blogged about a project : ‘rebuilding a home, and changing the surrounding fields from dead agricultural land into an oasis of natural life’ – as well as building an off-grid electrical and heating system. In this instance I used a clamp meter that will cover as wide a range as the current (amps).

Utility-scale solar PV pushes into higher AC voltages

Renewable Energy World

With output voltages now as high as 1000VAC, the same amperages will yield higher output power levels. Solar PV string inverters were initially used primarily in residential and commercial building applications up to 1MW in size. This was limited to traditional AC voltages of 120VAC single phase and 480VAC three phase.
