They told me that the microinverter was a proprietary device built by APS for their heater. They assured me it required no AC power source to work. See attachment, notice it has a variable AC output of 20 to 150 Vac. Also notice it can handle up to 620 Watts input. <div><br></div><div>I have not received and solicitation from them but was interested for off grid customers. They are showing "dealer" pricing to the public on their website. <a href="https://www.sunbandit.us/pricing.aspx#anchor-SBprice">https://www.sunbandit.us/pricing.aspx#anchor-SBprice</a> For those prices I'll use another method to heat water.<div><div><br></div><div>Larry</div><div><br>

Any first impressions? Here are my initial thoughts:<br>
</div><div class="gmail_default" style="font-family:verdana,sans-serif"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif">Pros - provides hot water in utility outages, no interconnection hassles, possibly easier permitting hurdles, eliminates moving parts in active SDHW systems</div>
<div class="gmail_default" style="font-family:verdana,sans-serif">Cons - no grid-tie, any excess energy produced is wasted, AHJs won't know how to categorize equipment for permitting and may charge for solar water heating and PV permits and inspections</div>
<div class="gmail_default" style="font-family:verdana,sans-serif"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif">I haven't dug too deep, but one strange thing I think I saw on a spec sheet was that the "micro-AC Grid" (aka microinverter) is UL 1703. If that is the case, how does the PV continue to provide water heating in a utility outage? What I really don't understand is why there is a need for a microinverter at all? Why not just use a DC element? I guess a microinverter, despite minor efficiency losses, is cheaper than a load controller.</div>
