- New owner of TenK technology. The rebirth of a famous solar technology.
- TenK site RE-Powering. Energy harvest recovery for existing arrays.
Solar built in parallel. Resilient by design.
Global RAIS® Energy & Storage Solutions builds modular, low-voltage, kit-based solar PV systems. When one cell fails, the array keeps working. That is the whole idea.
One bad cell shouldn’t take down the whole string.
Conventional panels wire cells in series, so a single shaded, cracked or spiked cell drags its entire group offline. Global RAIS® Smart Modules connect cells in a parallel matrix with module-integrated electronics, so each cell stands on its own. Try it.
Conventional module
Series cells, 3 bypass groupsEach bar is one bypass group of 20 cells.
Global RAIS® Smart Module
Parallel matrix + MIEDamaged cells are isolated. Neighbours keep producing.
Illustrative model. Global RAIS® spike testing shows about a 1.2% energy loss from a spike driven through a module, versus full group loss in a series-wired panel.
From module to grid, no single point of failure.
Serial strings fail together. Global RAIS® systems build current in parallel, through a redundant inverter bus, so one fault barely registers.
Advantages over conventional systems
Parallel cells, parallel system architecture and low-voltage DC. If a single device fails, everything else takes up the slack.
More power from the same square footage.
A whole-system approach: patent-protected modules, integrated racking and DC storage that is ready from day one.
Easy to install and maintain
Built to be installed by non-electricians with minimal training, which cuts labor cost on every project.
Higher energy density
Modules sit closer to rooftop obstructions with minimal impact, for up to 40% more energy density.
Low voltage, lower risk
30V to 59V on the DC side. Low-voltage architecture increases safety and reduces fire hazards.
Lightweight integrated design
Little or no ballasting needed, so the system stays light on the roof.
Efficient DC to DC storage
Works with most 48V batteries. Voltage is factory and field settable.
Greater durability
Cell-agnostic architecture with an aluminum back sheet, minimally affected by shade, delamination or water intrusion.
The detail behind every advantage
Our Technology Overview explains the original TenK architecture that Global RAIS® now owns: parallel cell matrix, redundant inverter bus, low-voltage DC and native storage.
Module, inversion, racking. One kit.
Our ultra-safe, resilient systems ship as a complete kit and adapt to off-grid and grid-tied installations, on rooftops, ground mounts and carports.
DC storage ready
DC storage ready
Everything in the box, engineered together
Module, module-integrated inversion and racking are designed as one system, which is why install rates beat conventional solar by more than double.
- Off-grid and grid-tied ready
- Rooftop, ground mount and carport applications
- DC storage ready out of the box
Patented Smart Module architecture
Parallel, or matrix, cell connections enable cell-independent performance. Module-integrated electronics (MIE) turn each panel into a Smart Module.
- Power point tracking within the module
- About 1.2% loss from a spike through the module
- Impact-resistant glass, aluminum back sheet
Proprietary parallel system architecture
Current builds in parallel, not series. If a single device fails, the rest of the system takes up the slack with only a minimal drop in output.
- No single point of failure across strings
- Redundant Inverter Bus
- Virtually eliminates complete system failure
Ballast-light, non-penetrating racking
An integrated, aerodynamic design normalizes wind pressure across the array, so most projects need little or no ballast.
- Under 3 PSF on most rooftops
- Delta Rail and Tubular Rail ground mounts
- Non-penetrating options
DC to DC efficient storage
Battery storage integrates naturally because the array is low-voltage on the DC side. The battery controls line voltage while the panels supply charging current.
- Charging range of 30V to 59V
- Fits most 48V battery storage units
- Factory and field-settable voltage
