Access to affordable energy is the greatest historical differentiator in development between societies. Thomas Edison strongly argued that DC was a better solution inside the home which was absolutely correct. AC is better for distribution to the home. Many modern devices and appliances already run on AC converted to DC internally from LED bulbs to induction cooktops, inverter refrigerators and dryers.
Focus is not energy savings but FREEDOM from the electrical umbilical shore power to enjoy the best places comfortably for Marine Vessels, Recreational Vehicles (RVs), a remote Cabin, or village in the developing world
A 48V DC System is Highly Recommended. However, we can also design and build the same for 24V DC if there is a compelling reason (rare). 12V DC is just too inefficient for anything bigger than a treehouse or small auto though of course 12v devices are supported.
Our design methodology always starts with sizing for 80% of days / conditions
- BTUs of 32+ SEER High-Efficiency 48V DC Air Conditioning / Heating whether you implement it immediately or not
- Total of all Loads.
- Recommend Induction cooktops, Air-fryer Toaster Oven, and Microwave.
- 48V DC Desalinator WaterMaker or freshwater Purification available and optionally use the solar array to collect rainwater
-
- Propane is recommended for high energy, short-duration loads: Instant Hot Water Peter to never run out, Clothes Dryer, and portable storable cooktop and/or grill.
- Prefer to avoid gas and do not need a clothes dryer? Then a Solar-direct Hot Water Heater is available requiring 1-3 extra panels.
- Size of Lifepo4 Battery Bank
- Size of Solar Array
- Small, fully automatic 3 to 5 kw 48V DC Battery Charging Generator to supplement running only a few hours 10% to 20% of days.
- Plugging-in can be done with any standard 120v 20a extension cord anywhere available.
We also design and build compact, indestructible, safe, and ultra-reliable LTO Batteries for infrequent, high-amp (>50a), short-duration, mission-critical loads such as engine starter, drive-by-wire joystick controls, windlass, thrusters, hydraulic pumps, elevators, etc.
