<p>Michael,</p>
<p> That's rather dis-heartening if boards are no longer available for a 10 year old product. Got a long day out of town today but will ruminate on responses.</p>

<div dir="ltr">I just pulled out an 8048 and replaced it with a 8048A due to the lack of AC boards for 8048s. I didn't know any better and put in a new 8048A board and learned the hard way that they aren't cross compatible. Smoked it. If you think you can find a board for it, it's yours.</div>

<div class="v1gmail_default" style="font-family: 'times new roman',serif; font-size: large;">Sorry if this is nonsense, but your existing Radian is your "AC grid source," It can act as the paralleling. </div>
<div class="v1gmail_default" style="font-family: 'times new roman',serif; font-size: large;">AC coupling source. I did this about 20 to 30 years ago, using FX inverters, not Radians, to power a large motor.</div>
<div class="v1gmail_default" style="font-family: 'times new roman',serif; font-size: large;">Can your Radian Mate 3 run in grid zero? Or if not, one inverter runs all the time as a grid source ( grid forming) </div>
<div class="v1gmail_default" style="font-family: 'times new roman',serif; font-size: large;">the second inverter (grid following) runs in Grid-Zero mode, with "off-set" set at 30 Amps. If the load is less than 30 amps, </div>
<div class="v1gmail_default" style="font-family: 'times new roman',serif; font-size: large;">the grid-following inverter carries the load. (The grid-forming inverter supplies the grid signal, and the following inverter </div>
<div class="v1gmail_default" style="font-family: 'times new roman',serif; font-size: large;">carries the load.) When your load exceeds 30 amps, the extra current comes from the grid-forming inverter. The Radian can </div>
<div class="v1gmail_default" style="font-family: 'times new roman',serif; font-size: large;">pass up to 50 or 60 amps from the forming inverter. You can get 50 to 60 amps</div>
<div class="v1gmail_default" style="font-family: 'times new roman',serif; font-size: large;">to the load when you add the forming and following inverters. Errors: this will double your parasitic load, I have not done this</div>
<div class="v1gmail_default" style="font-family: 'times new roman',serif; font-size: large;">so beware. This is not the answer for V2H; other inverters can work in this combination but </div>

<blockquote class="v1gmail_quote" style="margin: 0px 0px 0px 0.8ex; border-left: 1px solid #cccccc; padding-left: 1ex;"> The wrench list has some very creative thinkers that may have a <br />go around to be able to master/slave an old Radian's output with a new <br />one. Outback says this is not do-able. We're completely off-grid out <br />here and have been charging EVs (one at a time) with an eleven year old <br />Radian (GS8048) for years but the Ford Lightning is on its way.
