Volt Sensor Holder v1

thingiverse

Summary ==================== This voltmeter holder is designed to secure a voltmeter that disconnects my battery bank of my solar PV system when the battery reaches full capacity or a user-settable lower charge level. The use of this voltmeter is intended for overcharging prevention and discharging only 50% of my battery bank. It also sends a signal to a relay, which directs power from the solar panels to an inverter when the battery is full, preventing energy waste collected via the system. Relay I Use ==================== DC 12V Relay Switch Control Board Module Voltage Charging Discharge T https://www.ebay.co.uk/itm/DC-12V-Relay-Switch-Control-Board-Module-Voltage-Charging-Discharge-T-FJPTUKTW/392513997143?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 Features: Digital display DC voltage detection, controlling the relay output. Adjustable voltage limit: 0-99.9V. When measured voltage is lower than the lower limit or higher than upper limit value, the relay activates. Can be used for voltage detection switch, battery over/under voltage protection, or discharge meter. Notice: The relay control panel features single mode voltage detection function. Max trigger current is 10A(AC 277V, DC 30V), please don't connect it with load over DC 30V. This relay module is not suitable for lithium battery discharge. Polarity for voltage detection can't be connected reversely; user should connect the wire after power off.
