I completed a 2500 sq ft house in west Arkansas near Ft Smith about a year ago. I installed a Water Furnace 4 ton Geo Thermal HVAC system with 2 zones. It works great with a Sol-Ark 15K, 6.5 KW solar array, and 15KWH batteries. I think Arkansas does not get cold enough to be worth the expense of...

Yep, so no glass liner to crack, plastic outside so no rust and serious insulation. Works great it draws 4.8 KW when it on though, still easily with capacity of the solar system I have.

Noticed an interesting thing though; if I shut off the RSD by unplugging the transformer and then plug it back in, there is no voltage from the PV array ( actually 7 volts is let through by the RSD modules on each of the panels on the roof). If I turn of the DC on the inverter then plug in the...

After running for 3 days without incident; I tested the emergency shutdown function on the Sol-Ark today. In so doing the RSD power was removed, of course. After bringing the inverter back on-line I'm back to no power from the solar array. I have not been able to get the RSD to turn on. The...

Could not get the inverter to show any solar production at all. After fiddling with it for an hour or so: rebooted inverter, power on and off RSD multiple times, and turning DC on and off in various combinations. I gave up. This morning when the sun came up it was producing solar. No idea what...

I'm a beginner with solar but have been studing it for a few years; I'm installing a Grid Tied system consisting of Sol-Ark 15K, 16 Jinko panels and 3 Signature Solar batteries and APSmart RSD modules and transmitter. The batteries have not been installed yet as the rack is back ordered so...

I thought long and hard about spray foam. The cost was huge and then there is the choice between open and closed cell. Open cell is much more affordable than closed cell, but open cell will absorb and hold moisture. Moisture and mildew really had me worried. In the end I went with fiberglass. I...

Humidity was my biggest fear. Humidity control seems to be more of an art than a science. I erred toward a less tightly sealed house rather than risk to much moisture being trapped in the walls. The geo thermal HVAC I picked was largely because it offered a variable speed compressor and fan...

I'm answering my own question, I think. I rewired the APSmart transmitter so it was outside the house rather than just below the inverter. I also ran the positive PV cable thru the RSD transmitter output twice (should have increased the signal strength coupled into the PV wiring). This seems to...

The grid was/is up. The Tigo and APSmart are pretty much identical. I've powered the RSD transmitter from a 12 volt transformer plugged into and outlet in garage near the inverter.

Yes, the HVAC is connected to the water heater. Some of the excess heat produced by HVAC is pumped into the water heater. To take the max advantage of this feature you need to consider the hot water heater you use. I decided to go all electric for my house so used a Rheem Marathon 105 gallon...
