We have really been impressed with our DPUs and their ability to power our whole home during outages. To give you some context-we have 2x DPUs with 3 batteries each for a total of 36kW. Because of the location of our main service panel, we simply did not have the flexibility to get a SMHP2. Our basement is finished, our 200 Amp main panel is in the corner of our laundry room of all places. Right next to the dryer and washer (you can see the dryer in the pic below). It is crazy to me why they would place everything in that corner of the house when it was built back in 1993 but they did. I was quoted thousands of dollars to relocate my service panel and almost as much to install the SMHP2 and they would need to tear up some of finished basement walls. That was a no-go.
So we found some excellent sales with Outbound Power and had our DPUs in a couple of weeks. We went with a simplified set up using the 50 Amp Hub, interlock switch, a double throw switch and 50-amp inlet. We run a 50-amp cable from the hub to the inlet. My wife did not want me to mount the hub on the wall, so I built a little stand for it. It works like a charm.
Trying to find the limits of our set up this past weekend, I connected the DPUs and ran the entire panel, no managing loads at all. At one time, we had the heat on upstairs and downstairs (two 2-ton heat pumps), the oven, washer and dryer were used, lights, water heater came on as people showered, TVs, etc, etc, etc. Basically, we had a full load of house totaling 10kW+ (pic below) and the DPUs did not miss a beat. This tells me that for extended periods of outage and managing loads, we can definitely go a day+ using these if need be. This gives us some great flexibility for power back up between using our dual fuel generator and DPUs.
My plan for extended outages is to use my external inlet for my generator during the day and in the evening shut it down to secure it. Then switch to the DPUs inside for overnight to avoid worrying about a running generator. Our goal is to get 4 more batteries and get to 60kW. I LOVE THESE!!!
