Out in southeastern Washington, we recently wrapped up an off-grid system designed for reliability through all four seasons.
This project is part of a larger whole-home renovation, with a focus on long-term expandability, and we’re excited to be a part of helping bring that vision to life.
The system features a 3.84 kW ground-mounted array using 640W REC Group panels, built with APA Solar Racking Geo-Ballast baskets, allowing us to install without ground penetrations while still engineering for the heavier snow loads this area sees.
Given the remote location, we made a slight adjustment from our typical install approach. Instead of using 4–8 inch river rock in the baskets, we opted for cylinder block to simplify logistics and ensure a solid, stable foundation.
On the power side, the system is built around an EG4 energy management system incorporating the 6000XP off-grid inverter, paired with a 100Ah wall-mounted battery, and backed up by a 10 kW generator. The system is configured so the inverter can automatically call on the generator when needed, whether that’s to recharge the batteries or provide additional load support during extended periods of low solar production.
This kind of setup provides dependable, year-round power with an extra layer of resilience during those darker, colder Washington winters.
A big thank you to our crew for making this one happen. Four days on the road, working through every condition, and getting it done the right way. We appreciate the effort and the pride they bring to every project.
Projects like this are a good reminder that every site calls for a slightly different approach. Off-grid especially is never one-size-fits-all, and getting it right upfront makes all the difference.
