Frequently Asked Questions (FAQ)

The E-Maxx is a microcontroller for remote monitoring, controlling and configuration of the following devices:

“Selectronic” Inverters (SP PRO series 1 or 2)

“Capstone” gas turbines

It is not limited to the above devices, with the potential to remotely connect to other devices like generators and household appliances such as fridges, washing machines and air conditioners.

Power supply options for SP PRO inverters are via a 240VAC to 5VDC plug pack or a 12VDC to 5VDC adaptor which can be powered from the SP PRO’s 12VDC internal supply. Older SP PRO inverters without a USB port can be connected with the approved RS232 to USB adaptor from Aten, model US-232A.

Power supply for Capstone turbines is via a 24VDC marine grade cigarette lighter socket with a 24VDC USB car charger adaptor.

If you have a fault with the USB power supply, you can replace it with any brand provided that it supports the power source. Most cigarette lighter USB power supplies work with 12/24VDC, but it is wise to check.
