FOR SALE: Complete Off-Grid Power System — Ex-Telecom Site, Fully Proven in Service
Rock-solid remote power system, pulled from a decommissioned remote telecommunications site where it ran for years keeping critical comms gear alive through everything the backcountry could throw at it. If you're building a cabin, a lodge, a research station, or any off-grid setup that can't afford to go dark, this is a turnkey power plant that's already logged its break-in period and then some.
Prime Power — 2x Kubota Z602 Diesel Generators (Custom Build)
Twin Kubota Z602 diesel engines, each fitted with a custom 200A 24V alternator and Balmar external regulator for smart, adjustable charging — none of the crude on/off charging you get from stock alternators. Each genset is controlled by a Dynagen TG350 controller, giving you real engine monitoring, protection, and auto-start/stop logic rather than a bare-bones setup. A Morningstar relay driver handles the automatic start/stop sequencing and low-voltage disconnect (LVD) logic based on battery state, so the system starts the generators on its own when the bank needs a charge and shuts them down when the job's done — no manual intervention required. These two gensets were the primary charging source for the site, engineered to carry the full battery-charging load reliably in all seasons and light conditions. Having two independent units also means built-in redundancy: run one while servicing the other. These little Kubotas are legendary for reliability and fuel economy, which is exactly why the telecom industry leans on them for unmanned sites.
Fuel Storage — 800L Dual Containment Tank
Included is an 800 litre dual-containment fuel tank, built for exactly this kind of unattended remote application. The double-wall design means built-in spill containment with no separate bunding required — drop it in place and you're compliant with most remote/off-grid fuel storage requirements right out of the gate. Sized to give the twin Kubotas extended run autonomy between fuel deliveries.
Battery Bank — 12x Rolls Surrette 2V 1335Ah (S-1335 or equivalent)
A serious 24V bank built from true deep-cycle 2V industrial cells — 1335Ah at the 2V level, wired for a massive amp-hour capacity at 24V. Only three years old, so there's plenty of service life left. Rolls Surrette is the name flooded lead-acid battery purists trust for decades of service life when properly maintained.
Solar Array — 8x 175W 24V Panels (1,400W total)
Eight 175-watt 24V-rated panels supplementing the generator charging, helping offset fuel use and generator run-hours when conditions allowed.
Controls — Dynagen TG350 + Morningstar Relay Driver
Full auto-start/stop control package included. Dynagen TG350 controllers on each genset handle engine monitoring and protection; a Morningstar relay driver manages start/stop sequencing and low-voltage disconnect off the battery bank. This is the same intelligent automation that let the system run completely unattended at a remote comms site — set it up right and it looks after itself.
Why it's a smart buy:
This isn't a hobbyist system cobbled together — it's professional-grade telecom infrastructure, engineered for unattended, remote, high-reliability operation where a truck roll to fix a failure could mean a multi-hour flight or a long 4x4 trip. Every component was chosen for longevity and serviceability, not cost-cutting, right down to the fuel storage.
Condition: Site was decommissioned; system was fully operational at time of removal. Batteries are only two years old. Engine hours, battery specific-gravity readings, and full documentation available on request. Buyer should budget for a standard battery health check and fluids service before commissioning, as is customary for any used system of this type.
Ideal for: off-grid homes, cabins, ranches, remote work camps, research stations, marine/dock power, or anyone wanting a serious, redundant, self-managing power system rather than a single-point-of-failure setup.
Priced to move as a complete package — will consider reasonable offers. Local pickup preferred given the size and weight of the battery bank and fuel tank; freight can be arranged at buyer's expense. Serious inquiries only — contact for full spec sheet, photos, and hour meter readings.
