It's Time For A Subpanel Matched To Your Main Breaker


It is very easy to take the smaller 15 amp single pole loads out of your Main Breaker Panel and operate them for free using solar and wind charging devices, charge controllers, battery banking float voltage. With dc to ac pure sine wave microprocessor inverters that are so fast that computer/clock resets are not needed from voltage transfers of electrical power. 2 ac inputs island style connected and switchable. Example grid power and auto start generator power with options of additional solar wind.



The microprocessor inverters are the brains of automatic switching control as well as mixing different percentages amounts needed for voltage from different input sources 0% grid 100% autostart generator.The grid goes down from power outage and the autostart generator turns on automatically by the microprocessor inverter island style connection. This switching control gives options and manual settings also  This then allows the grid Main Breaker Panel to be used as a battery charger with ATS automatic transfer switching options. Banking lithium ion dc float voltage batteries in string sets can stop the grid tied meter from spinning for days or weeks before needing charging and are 100% sealed for zero gassing meaning they are safe inside your home as well as for climate control. Add solar and wind now the same microprocessor pure sinewave inverters have another source of automatic switching options. 0% grid 75% generator 25% battery bank inverter.

Pre set limits can be set as to which power source is the master and all others are slave with microprocessor control. Example grid shore power or grid camp ground power would trip the circuit breaker if the full load of the built in battery charger were made to operate the load. The microprocessor control has the answer by taking only a certain percentage from either source and adding the difference from other string sets of batteries, autostart generator, solar, wind. It is switching done by automation. And all this can be done over the web for free to have total control, monitoring, fault alerts by text or email and other options.



(1) Determine why the use or need for subpanel (example isolation from utility power but still have the ability to transfer power with island style ATS automatic transfer switch)
(2)  Main Breaker Panel 120 volt individual circuit  breakers located to subpanel (example: 15 amp single pole circuit breakers X ?)
(3) ATS automatic transfer switch Main Breaker Panel (example island style tap for monitoring connection, switching)


To isolate your Main Breaker Panel  from each individual 15 amp single pole circuit breakers for X ? amounts each wire, cable, NMB romex, conduit raceway item needs to be exact distance length plus makeup termination length for total length required to relocate to Subpanel. If the original wire is to short a termination box or gutter  that has access is the usual relocation method sizing original wire size to new exact same 100% example: thhn #14 solid black, white,ground,wire nut as required.

With sub-panel installed, circuit breakers wiring relocated the grid Main Breaker panel can still operate the larger 240 volt loads independently from sub-panel inverter power because the sub-panel is isolated from the grid Main Breaker Panel power. The only connection between grid Main Breaker Panel and sub-panel is ATS automatic transfer switch island style connected.

By starting small in building blocks of electrical power as you can afford the investment for the total outcome of which power source is the master and all others are slaves. Read past blog post and you will see that by adding options concerning electrical power are just that building blocks of electrical power.
