Unfortunately Jules Hendry's comment above is spot on. 90% of the people that work there are quite rude and this includes the response from one of their directors as well.
I have installed quite a few Microcare systems. I can honestly say that it is a descent product, very little issues as far as hardware goes.

UNFORTUNATELY their service is realy horrible. We have since stopped installing any Microcare products.

@GooseDI'm sorry to hear about your issues. And can only contribute to your agony. We have installed 4 sets of Omni power batteries and every one of these had failed well before the 1 year guarantee period. All with the same issues as described in your post. A battery monitor was connected to the last set of 4x OPR240s. I do not have the graphs with me at this moment, but can tell you that the highest temp recorded was 24 degrees, the lowest discharge rate was around 70% SoC. The highest charge rate was around 35A - 40A. Cycle wise, none of these batteries had more than 50 cycles at an average discharge of around 10% per cycle (90% soc). Two sets were credited under warranty, the 2nd last which coincidentally was connected to the battery monitor, was rejected. Within a month (during a single cycle) the battery monitor showed a total disacharge of eg. 30A and once charge completed (charge rate of less than 1A) the battery monitor would indicate only 91% SoC. Checking this it was noted that the recharge rate was almost always less than the discharge rate. This set off red flags. These batteries were returned to Sintech and the warranty claim was rejected. Their reason, possible overcharging. With a data sheet that claims 50A max charge rate and up to 60 degrees Celsius temp rate. That is kind of impossible.

The reality is that these batteries are really bad quality and the specs claimed in the data sheet is nowhere near the real values. I have had clients that used realy cheap rubbish batteries that lasted much longer than these under the same conditions.
