The book describes a stand alone solar energy system, made with a 24 Volt wet (open) lead acid battery and two solar panels from 200 Watt. A schematic from a simple power battery charger with transistors (2N3055) is published. It descibes how to get power inverters (24 V DC to 230 V AC, max 1500 Watt) into service with a simple soft start device. Schematics from switchboxes (switch between the AC grid and the AC inverter) are given. The approach is LOW TECH. More info can be found in the preview. IMPORTANT: on page 44 you find a trickle charger schematic. I found that the trickle charge values are too low for the Dutch solar situation given a permanent pull out of energy from the lead acid battery. Better values: 80 AH= 500 mA, 40 AH=250 mA, 20AH=125 mA, 10 AH=50 mA (these values given a for a constant use of energy from the battery). On page 79 pin 2 sets V ref, experiment with the 6K8 and 1K resistor (make them higher) for a better switch off moment.
