One board. Any battery chemistry — 18650, LiFePO4, or sodium-ion. Power that keeps flowing, day or night, for years without a site visit.
Field-deployed devices — environmental sensors, remote monitors, tracking units — live or die by their power supply. Solar panels and batteries seem like a simple pairing, but most off-the-shelf charging solutions are built around a single battery chemistry, tuned for a single climate, and unforgiving of the voltage swings real solar panels produce outdoors. The result: devices that brown out in winter, batteries that degrade early, and engineering teams stuck redesigning power electronics every time a project calls for a different battery.
Voltroot is a solar energy harvesting and charging platform purpose-built for unattended, fully off-grid IoT deployment. It pairs a power management platform recognized as one of the most efficient in the energy-harvesting industry with a flexible charging architecture that adapts to the battery you choose — lithium-ion (18650), LiFePO4, or sodium-ion — without a hardware redesign. Reliable power, indoors or out, with no grid connection and no wired power required, for the life of the deployment.
18650 lithium-ion, LiFePO4, and sodium-ion from the same board — choose the battery that fits your budget and climate, not the one your charger happens to support.
Automatically balances performance from weak overcast light to full outdoor sun — not tuned for laboratory conditions alone.
Continuously monitors and corrects its own charging configuration, so a voltage dip can't leave the system unable to recharge on its own.
Cold-starts from a near-zero power input, so a fully depleted system recovers safely on its own — no truck roll, no technician.
Battery health, charge status, and fault conditions report back to a central dashboard, so problems are visible before they become field visits.
A compact solar panel feeds Voltroot's energy harvesting circuit — from overcast light to direct sun.
The platform automatically switches between low- and high-power charging paths to stay efficient across conditions.
Charging parameters stay correct for whichever chemistry is installed, guarding against overcharge and unsafe temperatures.
Clean, regulated power reaches the host device, with status reported back to your dashboard.
Voltroot was developed alongside a live field application: a solar-powered environmental monitoring device deployed for continuous, unattended operation. That real-world use case — long deployment windows, unpredictable sun exposure, and zero tolerance for dead batteries — shaped every design decision, from cold-start behavior to remote fault reporting.
Building solar-powered sensors, monitors, or trackers for outdoor or remote deployment.
Running fleets of unattended devices across environmental monitoring, agriculture, infrastructure, or asset tracking.
Who want one power design to support multiple battery chemistries, instead of maintaining several.
| Benefit | What it means for you |
|---|---|
| Multi-chemistry support | Standardize on one board across product lines, regardless of battery choice. |
| Autonomous recovery | Devices restart themselves after full battery depletion — no site visit required. |
| Configuration drift protection | Charging stays correctly configured even through power interruptions. |
| Remote visibility | Battery and charge status reported to your dashboard, not discovered in the field. |
| Field-proven design | Developed and validated on an active outdoor deployment, not just on a bench. |
