Sounds like they need a 20 Kw Kohler. Hot Tub in the future? They'll love their Kohler. The Generac is just way too small to even consider IMHO.<br>

Gen support would be ideal but this inverter setup will be a quad pack of Magnum 4024PAE (120/240 split; 16kW). Their New MSH inverter is single phase only and can not be stacked.<br>
<br>
While disabling load(s) is the antithesis of the desired outcome, I'll review this possibility further.<br>
<br>
Using a separate charger could work but it would need to be about 200A @ 32V which would add quite a bit of cost and be hard to sell since the Magnum inverters already have 4 high quality charges included.<br>
<br>
A larger generator might be necessary if the customer won't agree to load shedding. Their plans are to expand the loads over time, operate a business, install a hot tube and more. Of course I have pushed the concept that conservation is paramount. The PV array and inverters are being oversized now for the future growth.<br>
<br>
My ideal solution...Since Magnum inverters monitor the AC input and control it based on quality of power, it seems to me that there could be a setting for disconnecting the AC input if loads exceed a setpoint. Change in control software would be great.<br>
<br>

Maybe a better approach might be to use an inverter with "Gen-support."<br>
That is unless a system already exists that does not have this feature.<br>
<br>
Plan B: use the gen start signal to disable one or more of the larger<br>
loads.<br>
<br>
I know this is not what you asked for, just trying inject some different<br>
ideas.<br>

Subject: [RE-wrenches] Generator automatic disconnect<br>
<br>
Wrenches,<br>
<br>
I want to use the Ecogen 6kW generator on a large off grid system. The<br>
location has very few overcast or rainy days and the generator will rarely<br>
be needed. My concerns is nuisance tripping the generator output breakers if<br>
the household load exceeds 6kW. The power system control has a feature for<br>
reducing the AC current used to charge the batteries but does not have a<br>
feature for disconnecting the AC input based on input load.<br>
<br>
Does anyone have a solution for monitoring AC load from the generator and<br>
disconnect it if overloaded? It must automatically reconnect after a short<br>
timeout.<br>
<br>
Thank you,<br>
Larry Crutcher<br>
