<p class="MsoNormal">The Sunny Boy Storage “Advanced Backup Unit” accessory or ABU will be discussed at SPI in a couple weeks – first units are being stocked now at our warehouses in US. The ABU will allow the SBS to be a grid former in case of utility outage,
however there are no plans to have any generator inputs/controls to allow for battery charging from generator.<o:p></o:p></p>

<pre><span style="color:black">><i> that would be to be able to charge the batteries off a generator in an<o:p></o:p></i></span></pre>
<pre><span style="color:black">><i> outage, understandably. But the extra thousands in cost for OB ended up<o:p></o:p></i></span></pre>
<pre><span style="color:black">><i> being prohibitive. Add-on rapid shutdown is a killer. So he’s opting for a<o:p></o:p></i></span></pre>
<pre><span style="color:black">><i> nice modern high voltage DC system, with optimizers and built-in RSD, but<o:p></o:p></i></span></pre>
<pre><span style="color:black">><i> when there’s an extended outage, he’ll have to hope the sun comes out right<o:p></o:p></i></span></pre>

<pre><span style="color:black">><i> again, until the grid comes back. Maybe there’s a high voltage inverter<o:p></o:p></i></span></pre>
<pre><span style="color:black">><i> that allows generator charging, or a third-party battery charger, that I’m<o:p></o:p></i></span></pre>
<pre><span style="color:black">><i> not aware of. Otherwise high voltage systems are very limited for backup,<o:p></o:p></i></span></pre>
