RYVAL Energy Services
UTILITY-SCALE BESS FIELD SERVICES

The standard others are measured by.

Commissioning, troubleshooting, and maintenance for battery energy storage — performed by senior field technicians under a written, BESS-specific safety program.

ANY OEM

Whatever your site runs on, we speak its language.

We aren’t tied to one manufacturer. We work across every major system in the enclosure and the yard — and follow your OEM’s procedures, so warranties stay intact.

Fault codes, IGBT and module issues, startup and parameter checks.
Battery & BMS
Cell, module and rack diagnostics, balancing and BMS alarms.
EMS & site controls
Site controllers, SCADA, Modbus, CAN and industrial networks.
MV & balance of system
Transformers, switchgear, relays, cabling and grounding.
HVAC & thermal
Enclosure cooling units, liquid cooling loops and sensors.
Fire detection & suppression
Gas detection, alarms and suppression system checks.

Every stage of the asset’s life. One crew that knows it.

From first energization to year-ten maintenance, we work alongside owners, OEMs, integrators and EPCs.

Commissioning & startup

Pre-energization checkout, startup, functional and integrated testing, and punch-list close-out — side by side with your OEM and EPC to reach COD.

Fault diagnosis down to root cause, in-scope component replacement, and a verified return to service — so lost megawatt-hours stop adding up.

03 SAFETY

A safety program written for battery storage.

A BESS is not a typical electrical install. Stored DC energy, remote dispatch and thermal events demand their own procedures — so your site, your people and ours go home safe.

Test before touch
HMI and SCADA status are never proof of isolation.
Every source, locked
DC, AC and remote control isolated and verified.
A JSA every shift
Hazards and controls briefed with the whole crew first.
Thermal-event ready
Clear response levels, evacuation and notification.
Stop-work authority · every person, every job

05 ABOUT

Hi, I’m Doug.

I started RYVAL Energy Services after years in the field commissioning, maintaining and troubleshooting utility-scale battery storage — from PCS and BMS to relays, controls networks, HVAC and fire systems.

When you call RYVAL, you get the person doing the work — from the first scoping call to the close-out report.
