<p dir="ltr">In my view, the real consideration here is whether or not the utility should be allowed to be the arbiter of how much capacity a homeowner is allowed to back up. My stance is no. They can't tell you how big of a backup generator you can have. Why should they get to dictate what capacity the customer has with regards to inverter size, assuming the system won't backfeed in excess of net metering limitations.</p>

<div id="m_9049126318112444205signature">Still Jason it seems very crazy! When I do energy for a home in your neck, usually offgrid, we use mini-splits and in a large home</div>
<div>like you are referring with the grid, the same thing, use a split for a zone, like the kitchen and save all that wasted battery capacity backing up the whole home. They may be a bit uncomfortable without the grid but they can survive a hurricane outage,</div>
<div>or longer.</div>
<div> </div>
<div>The strategy of not backing up it all does require the people to be reasonable and trainable. Very few central air systems are useable without spending 10's of thousands more. I think none unless the owner has more money than brains. Good for the economy I guess but all that lithium has to go to the dump someday. </div>
<div> </div>
<div>Seems alot of lithium is going to the dump with all these companies building batteries and then going out of business also.</div>
<div> </div>
<div>Alot of my calls are for systems that the installer has long gone out of business. The owner is clueless because they never had</div>
<div>a clue about their power system. No Bueno for sure! Stay Safe !<br>

If you size a backup system for central air conditioning, sometimes it is technically possible to heat the pool off-grid in the winter because the house load is otherwise a fraction of what it is in the summer months. In the winter, we sometimes see batteries full by 9:00 am and a lot of wasted solar energy.</span></div>

<div>Greetings wrenches,</div>
<div dir="auto">In Pacific Power territory we are coming up against roadblocks with regards to whole house battery backup systems with inverter ratings higher than 25kw. Even when the generation capacity is below the 25kw residential limit, net metering applications are being rejected based on the inverter rating.. The inverter rating in these cases is sized to handle the customer's existing loads and will never export more than the 25kw limit dictated by Oregon PUC. I am drafting a letter to Energy Trust, the state, etc. But am curious if anyone else gas had this problem or come up with a solution. I would appreciate to hear any experiences or similar interactions with PGE or PPL or even how this has worked in other jurisdictions, states, etc. Any input or support is greatly appreciated.</div>
