4.5.3 Connecting the battery to the Charge Controller and/or Hybrid Inverter
The battery terminals are positioned under the top cover. To open the cover, slide the raised latch to the right,
the handle will then pop up, rotate it counterclockwise 90° and lift the lid to the open position. Note: the lid does
not have a mechanism to keep it from shutting so be sure to open it past 90° or use an object to hold it open.
When connecting the cables ensure that the battery DC breaker is OFF and that the battery screen is off. Pay
special attention to the polarity of the connections and do not cross the positive and negative terminals between
the inverter/charge controller and the battery; also, ensure the terminals are not connected to any metal mounting
point, fixture, or body part.
The eVault Max is equipped with two 3/8s (M10) threaded terminals with a lock washer and nut. Recommended
terminal torque is 10.0 –19.1 N·m (7.4 – 14.1 ft.lb) The right-hand terminal is for the positive lead while the left-
hand terminal is for the negative. Heavy duty battery ring terminals of size 3/8s (10mm) along with proper size
wiring cables are required to connect battery to inverter/charger. Do not reverse polarity, doing so will void
warranty. Use a voltmeter to check polarity before connecting terminals.
