I Have No Internet, Where Can I Insert A Sim-Card?; I See Incorrect Current (Amps) Or Power Readings On My Ccgx - Victron energy Color Control GX Faq

Q3: I have no internet, where can I insert a sim-card?
There is no 3G modem in the Color Control, and therefore also no slot for a sim-card. Go to a local
store and buy a 3G router with Ethernet ports. More information in the blog post link below and
particularly in the comments section, as more users try differing equipment:

Note that it is not possible to use a VGR2 or VER for this. Also it will not be possible in the foreseeable
future.
Q4: Can I connect both a Color Control and a VGR2/VER to a
Multi/Inverter/Quattro?
No. Also, instead of this combination, we recommend to use the Color Control GX, and add a 3G or
similar mobile router. See the
Q5: Can I connect multiple Color Controls to a Multi/Inverter/Quattro?
No.
Q6: I see incorrect current (amps) or power readings on my CCGX
Examples are:
I know that a load is drawing 40W from the Multi, but the CCGX shows 10W or even 0W.
I see that the Multi is supplying a load with 2000W, while in inverter mode, but from the battery
only 1850W is being taken. Is those 150W coming out of nowhere?
The general answer is: the Multi and Quattros are not measurement instruments, they are
inverter/chargers, and the measurements shown are a best effort delivery.
In more detail, there are several causes for measurement inaccuracies:
1. Part of the power taken from a battery by the inverter is being lost in the inverter, converted
into heat: efficiency losses.
2. The Multi does not really measure the power being drawn from the battery. It measures the
current at the output of the inverter, and then makes an assumption of the power being drawn
from the battery.
3. Watts vs VA: depending on the Multi/Quattro firmware version and also the CCGX firmware
version, you are either looking at VAs (the result of calculating AC voltage * AC current) or
looking at a Watts measurement. To see WATTS on the CCGX, update your CCGX to the latest
version (v1.21 or newer). Also make sure the firmware version in your Multi supports Watts
readout, minimum versions are xxxx154, xxxx205 and xxxx300.
4. Multis/Quattros connected to the CCGX via a VE.Bus to VE.Can interface will always reports VAs,
not (yet) Watts.
5. If a current sensor assistant is loaded in a Multi/Quattro and no sensor is connected it will return
