All As a Beta tester and being a part of the development of the MNS All in One, MNS is working to ensure that the current limitations from the use of LA batteries will be addressed and supported.
MNS is addressing the concerns of using an AOI inverter because failure will require the R&R of the unit. This AIO is designed to be completely field serviceable and MNS will stock the boards and will provide the technical help to get the system back up and running in the field.
