Recently our voltage would drop below 165v and knock out our AVR so we bought a new 15kva transformer from Polaris for 68K php. When asked about refurbished units they mentioned they would not sell refubished ones since there is a greater chance of failure. Once tested by Polaris we took the test results to the Noreco main office to schedule its installation and paid the 300php installation fee. Installation day took another 4k php for additional wires, they hoisted the unit up the pole with a hoist pulley block, hooked it up the the main line and we have been a constant 220v ever since.

 

I sure think it would be. I'll be getting a couple of estimates for just such an install in July. I will start with just battery backup, with the Noreco supply charging them, then add panels later. I'll make sure to get a proper hybrid controller to properly account for the panels later on.
