Article on Project Using HiQ Inverters, SolarPro Magazine

We were delighted to be mentioned in this month's SolarPro magazine. This was through use of our 208V TrueStringTM inverters on a project by True South Solar in Ashland, Oregon. Our inverters and AC Splice box are shown in the photo below.

SPI Show - HiQ at the Show

HiQ had a good presence at the SPI show in Las Vegas last week. This included our booth, where we used a rented Mini Cooper filled with inverters to show the power density of TrueString Inverters. It also showed their ruggedness, with the fully loaded car sitting on top of four more TrueString inverters.

Visitors came in all shapes and sizes.

Install, San Francisco

For those of you interested in different approaches that are used to mount inverters and splice boxes, here is a recently finished 552 kW rooftop install in San Francisco.

24th November, 2015

Install, Palo Alto

Here are some photos of the 412 kW install featured in SolarPro magazine as it progressed.


The install consisted of a number of carports (example in top photo), and several large areas of flat roof. There is also an entranceway canopy where the cosmetics were important and there was no convenient place to mount inverters. In this case the flexibility of the TrueString was helpful: Two are mounted down in the electrical room, with longer DC string wiring running up to the canopy instead of the more usual array mounting method.
