Log each bank’s health with date and time, ID, voltage, current, temperature, internal resistance, SOC, SOH, and capacity, plus notes. Record every charge cycle with start and end time, starting and ending SOC, and energy in and out. Convert Ah and Wh with ease, and quickly work out power from voltage or current. See how long a charge will take, and how long a load can run. Size your inverter with clear steps so your setup fits your needs. View all records in one place to spot trends and catch issues early.
