We received a Hawke's Bay MPPT Charge Controller last last week. And After a bit of an upgrade on our array, Hawke's Bay is doing nicely indeed. Running 10 panels in a string has yielded 90% energy to the batteries in full sunlight (2070 watts from a 2300 watt setup). The string has an MPPT voltage around 341 volts, this is not running HB very hard, but newer panels are on the way. We are looking forward to the increased production out on the farm.
HB is cool to the touch, this while it is "living" in our unconditioned barn in Hot and Humid Texas.
One or two Beta issues have been found and passed on to the "coordinator".
All in all first impressions are very positive. As the software matures, this MPPT charge controller should be very capable. One of the teasers in the menus is its integration with an inverter.... More to come on that in the future!
