After a months on and off work the new solar power system is finished. Below you can see the power control hut with the change controller and isolation boxes. The main battery Isolation box is open showing the wiring to the fuses, isolators and current monitors.
Solar power Hut
The Current monitors are home made units based on a signal chip current measurement ic ( ACS754SCB-100-PFF ) . One of the units are shown below. It consists of the IC mounted on a peace of veroboard with the line contacts solders into two connecters that I removed from some fuse holders that we brought by mistake. (As normal on this island you can buy a car audio fuse holder that no one sells fuses for). All of this is mounted on a home made Perspex mounting panel.

The last thing that we done is mount the current solar panels on our adjustable panel mounts and connected them to the power hut.
