The connection of the battery, conduct oneself, is properly documented and easy to do.
Use single inverter mode is very simple: you plug in the right serial socket, specified in the instructions and on the inverter recalled, is enough to take advantage of the product.
The software and the supplied cables are used to communicate the inverter and the computer so that it turns off itself when the power is off.
If you are, like me, user of a Synology NAS, UPS and NAS can communicate with each other with a connection and a walk in the configuration of power in DSM, no additional software.
The power saving mode, which turns off several more taken when the device connected to the master socket is switched off, allows to automatically power on and off devices on a desktop computer: when you turn the tower and screen other devices are switched on automatically, and switches off when the tower while cuts to best conserve power.
Only drawback, the product is quite heavy because of the battery in it.
