I had an earlier posting on system grounding and this is partly in response to some of the suggestions in that posting. System description. 25 ft head. Variable water flow from 75 to 175 ga. per minute. Turgo runner. [homemade with spoons from h-hydro] F&P smartdrive rectified at the turbine. Total output 100- 350 watts depending on the volume of water. There are two wires coming from the generator. 4/0 cable [salvaged] 300 ft. running on the ground to the house. 48 volt battery bank. Matrix 5000 UPS as inverter. I have a question about how to connect the charging circuit, batteries and UPS. I now have incoming current , charge controller, UPS and battery positive connected to a terminal block. The cable to the positive terminal of the battery is protected by a properly sized fuse and dc disconnect. All circuits are likewise protected by fuses and have disconnects. Have I done something wrong here? My thinking was to protect everything from a battery short circuit, but some advice seems to suggest that connections should be direct to the battery terminal . Thanks for any advice or help or perhaps links to photos or diagrams showing the details of a system properly wired . I've searched a bunch but have only found vague diagrams with no details. I'm still without ground wires but will be running some , I hope before the next thunderstorm.
