How do I add an inverter to my eSYSTEM?

All Enerdrive eSYSTEM DIY Installation Kits that do not include an inverter mounted on the board can be adapted to fit an inverter separate to the board, some systems have a pre-installed breaker to suit this purpose, whereas others may need to be installed separately. When adding an inverter to your system, you should take the following factors into consideration:

Cable Size
Most inverter related problems are the direct result of running cables that are too small. Because inverters are such a heavy load on your system they need to be installed as close to your eSYSTEM as possible and need to have large diameter cables.

Battery Size

An inverter represents a heavy load on your electrical system and you will need an appropriate sized battery bank in order to run it. Lithium batteries excel at maintaining voltage under load, which makes them ideal for running inverters. You will need to ensure that the current draw of your inverter does not exceed the maximum allowable current draw of your batteries. More information on choosing suitable batteries for your inverter can be found here.

Cable connections
If you add an inverter to your eSYSTEM, you will need to ensure that the cables are run correctly. 

The negative cable of the inverter should be connected to the "SYSTEM" side of your battery monitor, some eSYSTEMS may have the 3 Stud M8 Bus Bar on the "SYSTEM" side of the battery monitor shunt that you could also connect your negative to.

Your inverter negative will be one of the heaviest cables connected to this bus bar, and therefore it should be at the bottom of the post if you are stacking multiple lugs (like a pyramid or Christmas tree). Failure to connect the inverter to the "SYSTEM" side of your battery monitor will prevent accurate current measurement and will cause the state of charge reading to be incorrect. Your inverter positive cable should be connected via a circuit breaker or fuse to the positive of your system, ensuring that the cable size all the way from the battery to the inverter is appropriate for the loads you intend on using.

An example of the proper connection points for an eSYS-G can be seen below. The connection points are also shown in the system wiring diagrams, which can be found here (under the downloads tab).
