As Simple As A Sunrise

Your grid independent power needs Simplicity

Whether your power need is a home in the wilderness, a townhouse complex, village electrification in a developing nation, a military forward operating base, or anywhere the grid is unreliable — Simplicity™ is the most cost effective solution for solar independence.

The Digital Microgrid Initiative is a public benefit corporation started by leading power electronics and energy storage technology companies to provide a new kind of solar power system to specifically address the needs of developing nations.

Simplicity is a family of products designed for rapid, cost effective solar independence - no costly installation or custom engineering. Simplicity consists of four mix and match components: a self-governing battery pack, 100A smart breaker AC panel, self-governing solar panels, and a grid/generator connection for backup. These parts connect with a single cable, and can work in any combination.

DMI 24 kWh system

Start small. Grow simply.

Start without batteries, or just a few to provide nightly power for an average home; expand to power a whole neighborhood or village. Start with no solar panels to just use your batteries as backup for grid power, or fill a whole field and share power within a cluster of buildings. You can mix solar panel sizes and orientation without worrying about clouds or shadows.

A totally off-grid solar power system for a "tiny house", cabin or RV can be installed for less than $12,000. A small passive home designed for 100A electric service can be NetZero Energy for less than $14,000. An average U.S. home with 200A service can eliminate electric bills forever for $26,000. With Federal and state rebates, these system may cost you 30% to 40% less.

On a larger scale, a 60-unit condo complex with shared solar array and shared energy storage can be installed incrementally as the units sell and be totally off grid with a cost per condo of $7,000.

The Applications

We've been working with cutting-edge battery storage since 2008, and our battery management, control systems, and intelligent distribution is unrivaled in the industry. While there exist other energy storage systems on the market, none of them are designed with modular scalability at their core.

Tiny houses come in all shapes and sizes. While an average home may need a 100A or 200A service panel, a one or two bedroom tiny home might get by with 25A or 50A. The flexibility of Simplicity lets you tailer to the limitations of the small size while providing an expandable solution for particular needs. This home is 1200 square feet with tight construction. It has roof space for eight panels providing 12 kWh per day, just enough with heating provided by a wood stove. Two kWh of energy storage plus a 16 kW inverter plus eight 330 watt home-owner installed panels have a project cost of $12,900.

This all electric, three-bedroom home is built for energy efficiency and is powered by twenty-one 330-watt 380 volt solar panels. A 32 kW inverter powers the 200A breaker panel and four 12 kWh 380 volt batteries provide power through the night. The electric grid or a generator can supplement the solar power as a backup in case of extended bad weather. Total project cost including solar installation is $43,100.

Zero-net luxury condo complex

This complex of ten luxury condos is powered by four separate PV arrays with different orientation and some shading problems. Each of the 114 330-watt panels has individual MPPT control and the panels are connected in parallel at a nominal 380 VDC. For nighttime power, there is a centralized 90 kWh energy storage bank. Each condo has its own 16kW inverter and 100A distribution panel. All power through the complex is distributed on a 6 AWG pair of solar cables with MC4 connectors for each of the components in the system. The system can be expanded by simply plugging in more panels in any of the PV strings, adding more batteries or increasing the number of condos installed. Total project cost including installation is $130,000.

Village electrification

Start small and add power as needed or as budget permits. Initial cost of the project is $4,630 including the inverter, panels and installation. This village power system, due to budget constraints, only provides power during the daytime. However, it can be easily expanded for higher output and nighttime operation by simply plugging in Simplicity Battery Modules. The first logical expansion is the addition of a 8kW/ 12 kWh battery module for an additional $4,688. No installation or reconfiguration is needed to expand the system. Simply plug in additional PV, batteries, or inverters as needed to the single-wire backbone.

Community solar

A desert community powered totally off-grid by 600 ground- mounted, thin-film solar panels. Total solar output is 680 kWh. This array provides power for 45 homes and businesses. Power is provided through the night by 40 Smart Batteries. Power is distributed among the various locations on a low loss DC buss and each home has a 16 kW inverter feeding a 100A service panel. The total installation including panels, ground- mount array, a containerized energy storage bank, costs $216,000 for the installed PV; $130,400 for 45 16kW inverters, and $351,000 for 600 kWh of containerized, climate controlled LFP energy storage. Total for the project is $698,000.

Remote monitoring

Each module provides Bluetooth-enabled cloud-based monitoring from iOS or Android devices. In addition to reporting current and historical status, inverters and distribution controllers maximize backup power available or optimize off-grid energy consumption.

DMI believes in and contributes to open standards and will be supporting ongoing energy management standards efforts as well as proprietary communication from NeST, Honeywell, IBM, Schneider and others.

Engineered in the U.S.A. and built where you live

We are all about providing power around the world, wherever it's needed. We also understand that emerging nations need jobs and technology. Our business is modeled on the distribution model of Coca Cola and Pepsi. Our Digital Microgrid 'bottlers' are your neighbors. They are building independent assembly plants in your country to assemble our power systems where you live.

Designing your Simplicity system

This estimate is based on an analysis of homes similar to yours in your area. It is intended as a guide and is based on limited information about the construction, orientation to the sun, roof slope, lifestyle, and many other factors. Estimated cost includes installation, racking and mounting and assumes typical U.S. cost per installed watt. Your cost may vary depending on local conditions. Estimate does not include shipping or duties.

Provide the information for your home in the boxes and sliders below. If you are on the electric grid, compare the energy requirement against your monthly bill. If your location is not included in the list, pick a spot with similar weather. We're continually upgrading our climate and electric rate model and will be adding locations outside of the continental US soon.

How is your house heated?
Your heating, cooling and hot water account for about half of your total energy consumption. Selecting "All Electric" sizes your system to handle these loads
Where are you located? Select your state from the pull-down list.

How big is your house? Use the scroll bar to select your home's square footage or take a guess from small to large

How energy efficient is it? If you are unsure, we can provide some guidelines. How well your house is insulated has a very large impact on energy use.

How much of your electric load should your panels and batteries supply? Your solar panels and batteries can handle part or all of your electric requirements during the day. However, if less than 100%, then you will need to supplement with additonal batteries, generator or grid backup. A system designed to handle the daily average kWh will rarely need backup power.

How much of your electricity consumption needs battery backup? Your solar panels only provide power when the sun is shining and then full power is only provided mid-day. The rest of the time you'll either need to restrict electric use or have enough battery backup. Also, if the system is off-grid and without additional backup power, you'll need enough batteries to handle all your simultaneous power loads.
