This build follows the replacement of an older off grid solar system.
Key benefits
- improved system efficiency. From 65% round trip to 95.
- greater solar output
- clean pure sine wave of a modern inverter runs all home appliances and is easy on motors.
- less maintenance. The new Lifepo4 battery needs no maintenance.
- high reliability. No operational concerns for another 20 years.
- better reporting. The system is designed to talk to itself and monitor its use and behaviour. Want to listen in? Wifi reporting allows easy access to system status, from anywhere.
- increased efficiency means less generator time in the winter.
Key system elements
- New transformerless inverter topology means unparalleled reliability and flexibility.
- 5kw single phase 120v
- Latest Lifepo4 battery is the safest and longest lived battery available today for home power use.
- 5.1 kwh battery with R485 reporting. Two modules.
- New inverter and battery communication reduces installer headaches and improves ease of use.
- Doubled solar panel output with bifacial panel. This new technology reduces winter solar loss from 16% due to snow/cloud to 8. Bifacial panels melt snow off faster as a result of back panel warming. Add 50-100w of power off the back panel. Snow albedo becomes your friend.
- 450w. 4 panel array. 550w winter?


The older system was extremely well built. One of the best I’ve seen. So why change it out?
- modified sine wave inverter doesn’t run clothes washer. Note: Square wave sine signals are very hard on motors. Owners report short fridge lifespans.
- batteries at end of life
- solar array capacity is low and needs a winter boost
- customer also wishes to have a lower maintenance system
