(mine is lower amperage) for a couple of years. It works very well. No automatic 100% charge state setting on full charge but it needs only very minor adjustment in the amp-hours stored after the post-trip full charge. It indicates direction of current flow with a charging light and automatically integrates either direction to amp-hours charging state correctly.
My only caution for anyone considering this is that my 25 amp unit has terminal screws barely large enough for AWG 14 wire. Hopefully the 90 amp one has bigger terminals. And an external shunt could be used to avoid the problem. It's no problem for my 6 amp solar panel, similar engine or converter charging, and no large loads.
I made some mistakes in estimating the state of charge with a voltmeter that cost me a good deal more than the price of this excellent battery monitor.
