NMS044 Power Draw
A-2
A.2 NMS044 Power Draw
The NMS044 system draws power from the connected battery. It cannot
be powered any other way (ex. wall outlet).
The following table was generated from the recommended setup for
the RV50X, see “Preparing the Battery” on page 2-1. Other options are
available that will change the power consumption of the system and
any deviation from the recommended setup. Setting up scheduled run-
time(s) on the 831C meter will cause the meter to turn off when not
running which will extend the number of days of backup.
All of these values are given with the assumption that no external
power is attached (solar, outlet, etc.).
A.2.1 Sunlight Hours
You are encouraged to take advantage of the most daylight, direct sun
for your area. To better understand your sunlight, refer to

A.2.2 Alternative Solar Panel
The NMS044 system can support solar panels that are <140 W.
A.3 Long Term Storage
If your system is to be stored for more than one week, unplug and/or
remove the battery from the case and store separately.
A.4 Shipping Information

Do not transport with
lid open.
