Phocos’ DINGO charge controller has a negative ground that makes it a great option to be used in vehicles. Its communication interface uses the MODBUS protocol, which has been tried and tested in harsh environments. The DINGO’s large memory tracks data such as charging Ah, load Ah, battery voltage range and the daily state of charge for 512 days. The data of the past 99 days can be accessed directly using the built-in LCD display with LED backlighting.
