Nice
It is a nice product though I have reservation about the firmware which detect over voltage(morning voltage spikes) at 400vdc resulting to zero ampere generated from arrays. Firmware is suppose to let grid power to charge batteries if there is but won't let it(grid) but just stay there, not charging batteries from arrays and not allowing grid to charge batteries until the sun is able to warm the arrays then everything return to normal. Other than this, it is a very good product.
