Purchased the SHP3 along with the DPUX + 4 batteries, Flowmaster Generator Rectifier and could not be happier. Install of the SHP3 was straight forward, and any licensed and certified electrician can install it without issue. My electrician that I've used for other projects had the SHP3 installed and fully functional within 6 hours. Permitting is not a heavy lift either, as I replaced my existing 200a main service panel with the SHP3 and the electrician handled the two phone calls it took for permitting and to have the electric company come out and pull the meter. I am currently using 31 of the 32 circuits and have had no issues with it handling the load of a 4 ton A/C unit, electric water heater, well pump, water purification system, electric oven, electric range, etc.

This is the product we have been waiting for too bad there's not one single person who can talk about how to design intergrate and find an Installer for the heavy lifting permit parts of this system in the North Eastern The Extreme Price is quite a turn off for exactly that reason get your selves together and perhaps people can actually use the whole home solar battery backup that is reportedly a 32 slot smart pannel to manage your home energy usage (like an 8k span pannel) for 1/2 the price that works with ecosmart's DC coupled inverter tgat has ability to charge a car with a DC to DC charger and requires no permit due to the unmounted upgradable mobile battery stack format.
