Software
When a new RESS is installed, verify the latest software is installed. Use DTII to check and update software.
When updating software, attach a lithium ion charger (minimum 5 amp) to the 12V back-up battery. The software update may disable the onboard charger. If so, the 12V backup battery may not supply enough power for the software update.
If replacing a RESS, use the box from the new RESS to return the old one. The top of the box is heavy. Use two people to lift the box top.
