Take a look at Sonnen ecolinx, it can be used in a smart home with the proper communications option.

A typical home’s energy use is ~40% electric (kWh’s) & 60% thermal (BTU’s).

These inverter/battery systems are really standalone components of a residence’s energy infrastructure. They do what they do supplying supplemental and back-up electrical power without regard to anything but the supply and demand.They do not interact with any of the other components of the home’s infrastructure leaving the homeowner to control the demand from the other standalone components like HVAC, DHW, pumps, etc.

A complete residential energy system needs an overarching intelligence that interacts with all the infrastructure components creating, storing and managing both electrical and thermal power throughout the residence. To accomplish this both an electric and a thermal grid are needed.

A thermal grid operates just like an electric grid but uses pipes, pumps, valves and thermal storage rather than wires, switches, and batteries to distribute thermal power. Like batteries store excess electric energy but far less expensive and much longer lived, thermal storage stores BTU’s efficiently for use when needed. A thermal grid distributes those BTU’s to whatever system is calling for heat (or cold). The nexus of a truly complete residential energy system must interact with all the energy infrastructure components both supply and demand, electrical and thermal.

Right now, in the solar PV industry amongst the many different applications from utility scale solar PV farms to residential installations, it seems like over the last three or so years there seems to be a ‘merger’ of the simple grid tied system of 10 years ago and more integration of energy storage in new systems installs. The movement is towards the ability to become aggregate VPP systems with buy/sell energy coming as a signal from the grid itself. These systems have evolved over the years into micro-grids in their own right.

Looking back just a few years, in 2000 a simple solar PV panel string to grid tied house inverter(s) could cost up around $70K for a 9kWp system. Now, even without the ITC of 26% one can get a relatively large solar PV array around 10.5kWp and a smart ESS with something like 30kWh energy storage for around that same $70K today installed, not taking into account one still has a federal tax credit of 26% of the entire system cost off of one’s Federal taxes.

California is pushing the envelope with the IOU electric utilities and their tiered electricity rate programs and TOU rate programs in place. In California the residential electricity rate is an “average” of $0.20/kWh to $0.25/kWh. Many in the U.S. are still bragging about they ‘only’ pay $0.09/kWh today. Well with mandates like decarbonization of the U.S. grid by 2035, there are going to be a (lot) of electricity rate increases across the U.S. from now on. Sooner than later that $0.09/kWh electricity becomes $0.27/kWh as old generation facilities are decommissioned and new generation facilities are constructed. The electric bills of many will rise when the electric utilities start filing electric rate increases from many “stranded assets”. The question is on the individual level, “how much will you tolerate” until you buy your own generation and energy storage system to use in your home?

The people coming and looking for help on how to DIY Solar Systems and even LFP Battery Packs has been escalating exponentially. With the latest “Pile” out of California USA a LOT of Californians have popped up. Something about $8 per kW of Panel fees and FIT being dropped to something like 0.04 Cents per kW sent to grid… Sure fire way to get folks OFF GRID !

The WORLD NEEDS Affordable LiFePO4 Battery Banks for our homes & businesses. LFP IP is up in March this year, global production is queuing up, raw resources have to be obtained and time to put the Fossil Resource Funded Nimby’s off side into their place…

I live nearby a Solaredge facility in Italy, and i see how it has grown in few time. Then, I bought some stocks with the purpose to mantain long time my position. Nowdays all solar stocks in USA are struggling. Is the lack of BBB approval one of the reasons for It? If yes, Is there any chance to overcome this BBB issue, by other solar incentives?
