Off-Grid Solar & Battery Power Systems
Real, catalogued equipment for cabins, land, remote structures and docked marine sites with no utility connection - hybrid inverters, MPPT charge controllers, and battery banks sized to your actual load.
Tailored for DC, Maryland & Virginia climate, net metering codes, and local utility regulations.
How It Works
Four steps, start to finish -- no guessing what happens after you reach out.
Load calculation for your site
We size your battery bank and any backup generator off your actual daily energy use -- not a fixed default -- because there's no grid to fall back on.
Catalogued, priced equipment
Inverter, charge controllers, and battery bank selected from real bill-of-materials equipment matched to your array, not estimated from a per-watt rule of thumb.
Local electrical permit, no utility paperwork
We handle the electrical permit for the install itself -- there's no utility interconnection application, since the system never connects to the grid.
Installed and commissioned off-grid
Hybrid inverter, battery bank, and any backup generator wired in and tested to UL 1741 / UL 9540 standards before you rely on it.

No obligation, no pressure -- just what this would actually look like on your property.
Off-Grid Technical Specifications
Core engineering, component sizing, and hardware standards
Battery-based inverter/charger delivering real US split-phase 120/240V, sized to your array and your load rather than a per-watt allowance.
Added when the inverter's own MPPT input is smaller than the array, sized off each controller's published, temperature-derated charge current.
Capacity comes from your actual daily energy use, not a fixed default - a load calculation is part of every off-grid design.
Rated at or above the inverter's continuous output, paired with a service-entrance-rated automatic transfer switch.
DMV Tax Credits & Incentives
Federal, state, and utility benefits for Off-Grid
Solar and battery storage at your residence qualify under 26 U.S.C. Section 25D - off-grid systems included, since 25D carries no grid-interconnection requirement.
Business-owned remote sites, agricultural operations and off-grid commercial buildings qualify under Section 48 (30% Base + 10% Domestic Content + 10% Energy Community).
An off-grid system needs no utility application, interconnection agreement or net-metering paperwork - it never connects to the grid.
Once installed, solar and battery serve your load at no fuel cost; a backup generator, if included, is the only ongoing fuel expense.
Why Choose Off-Grid Solar in DC, MD & VA?
Real Bill-of-Materials Sizing
Inverter, charge controllers and any generator are selected from catalogued, priced equipment matched to your array - not estimated from a per-watt rule of thumb.
Split-Phase 120/240V Output
Every inverter we install delivers standard US split-phase power natively, so it runs ordinary 240V appliances without a second unit or added interconnect hardware.
Load-Calculated Battery & Backup
Battery capacity and any backup generator are sized to your largest simultaneous load - well pump, HVAC compressor, range - not just your daily average.
UL 1741 / UL 9540 Listed Equipment
Every catalogued inverter is listed to UL 1741 (and UL 9540 where applicable) for safety and code compliance, not just wattage.

Go Solar DMV can't guarantee we can serve every off-grid system customer - some rigs, roofs, sites or locations fall outside what we can install, and we'll tell you plainly if that's the case rather than promise a system we can't deliver.
