Terms and Conditions

Prices and specifications subject to change without notice.
The buyer must agree that:

  • all installations shall be approved by a licensed electrician;
  • a previous user shall be available to advise and answer questions during installation and the buyer after successful installation agrees to serve as an adviser for at least one future user;
  • the user will not copy or facilitate another’s copying without approval.

(Note: the user shall receive a license to use the technology under several U.S. patents/patent applications.  Moreover, you will obtain an ownership share of rights of the trademark, which will gradually become more valuable as the technology spreads.  When you buy and use our product, you become a valuable member of our extended family!)

All of our products are “nodes” which can peer-to-peer connect to any other node and can input solar panels.  By inputting solar panels at each node without additional equipment, you can harvest huge amounts of solar energy over a spread out area without buying additional equipment and without any detailed planning.  You can use large amounts of solar electricity even when it is raining or overcast, as our node equipment efficiencies do not suffer at low lighting conditions, unlike AC systems.

The solar panels are series connected with Vmax (maximum power point voltages) that sum to 125-145 volts (in the U.S.) or to 105-140 volts (in Japan).  Solar energy harvested at these voltages can be used directly in most appliances (after pulsing to protect the switches) and avoids the high cost and inefficiencies of voltage conversions. Furthermore, this voltage range in DC power allows peer to peer node connections without adding inefficiencies or equipment, and allows self-regulation based on minor differences in voltages at adjacent nodes. This is the secret behind the higher efficiency, easy implementation and low cost of the community grid.

Basic Node Box

The Basic Node Box connects:
.     a. optional solar panel input
.     b. utility company power as backup input
.     c. appliances via “smart plug” outlets that provide pulsing DC power to appliances that
.          accept this power 
(this allows us to bypass inefficient and expensive voltage
.          conversions and DC-AC conversions used in
 legacy AC grid systems)
.     d. if ordered (specify voltage needed) a battery charging output, and
.     e. to other nodes (via simple wire) to form an energy web with others and with other
.         nodes that you can buy.


Dump Load Node Box

The Dump Load Node Box connects:
.     a. optional solar panel input
.     b. utility company power as backup input
.     c.  a water heater or other heater such as electric radiator, electric rug, infrared heater,
.          which automatically accepts excess power generated by neighboring nodes.ets that
.          provide pulsing DC power to appliances that accept this power

.     d. to other nodes (via simple wire) to form an energy web with others and with other .
.          nodes that you can buy.


We recommend adding our water heater node to power an inexpensive electric water heater (under sink unit to supply a sink or whole house unit for all hot water needs). Such “dump-load” will absorb all of that extremely cheap energy you will produce from your solar panels from time to time, and smooth out the load for optimum efficiency and minimize battery use. 

Inductive Node Box

The Inductive Node Box connects:
.     a. optional solar panel input
.     b. utility company power as backup input
.     c. inductive appliances such as refrigerators and air conditioners, and
.     d. to other nodes (via simple wire) to form an energy web with others and with other
.          nodes that you can buy.

Battery Backup Node Box

The Battery Backup Node Box connects:
.     a. optional solar panel input;
.     b. utility company power as backup input;
.     c.  a battery that can supply power to the local grid and power appliances such as
.          computers and televisions at night;  (the battery is charged by solar panels, grid
.          power or also by utility grid power) and

.     d. to other nodes (via simple wire) to form an energy web with others and with other
.          nodes that you can buy.

Dump Load Extra Box

The Dump Load Extra Box automatically dumps available but unused solar power
into two loads (to be continued)


The “Entry Level” System

This system is perfect as a stand alone system for a tiny house, as backup used in parallel with an existing electric power system to handle emergencies/power outages, and to  decrease reliance (and costs) on the utility grid.   In a stand alone configuration for cabins or tiny houses,  we recommend installing a water heater and node boxes just outside the tiny house, to optimize space.  In both applications, a backup battery system provides electricity for nighttime use of computers/televisions/cell phone chargers and printers, and for powering a refrigerator.

Components of the “Entry Level” system:

a. 1000 watts solar panels                                 cost:  $700
.    four 250 watt panels 33 Vmax
b. basic node box                                                cost:  $750
.    to power computer/printer/coffee pot/cell phone/small tools etc
.    and 12 volt lighting output
c. dump load box                                                 cost: $400
.    to power water heater, space heaters
d. inductive load box                                           cost: $700
.    power refrigerator, freezer
e. battery node box                                             cost: $400
.    batteries 30 amp hour X 100 volts               cost: $500
f.   wire/fuses/disconnects                                  cost: $250

Low Cost DIY Kits Available for
Evaluation and Community Building

See our “Community-Builder” page for information on purchasing our more simplified DIY kits, for those with experience in building, or who wish to acquire a skill in building simple power electronics  equipment.  The DIY version of our Basic Node box has the same automatic shut  off and grid/utility/solar-panels input connections, but lacks the built in battery charger (you probably already have your own), the exterior screw  terminals, and lacks the 12 volt power  output (again, you can supply that yourself, and we can show you how to wire in a 12 volt power adapter into a grid node).

If you go this  low cost route,  we recommend  that you  start out with one Basic Node box and one Dump Load box, and connect one of these two boxes  to 4  solar  panels of at least 200 watts  each having Vmax between 33 and 40  volts each.  You can  always add more panels, more boxes and grow  your system as you become comfortable with the  technology.

Our products do not follow mainstream and are designed for electricity savvy do-it- your-selfers who want to enhance the quality and resiliency of their lifestyle, or to build a business providing DIY Grid service to others. If you are afraid of electricity or do not want to learn basic electricity, then buying and installing DIY Grid on your own is not for you. However, even in such event please join us in your step by step journey to resilient community building.  Resilience begins with locavore (local food production) and self sufficiency in education, elderly care, water, and other community needs, in addition to the electricity aspects. We are part of a growing movement and need each other.
