Loads & energy
Daily Wh/kWh, continuous power, short surge, duty cycle and critical loads.
For small off-grid solar installers
Design the off-grid system before choosing the battery.
Share the load profile, autonomy target, solar window, inverter and site conditions. Outravira turns them into a product starting point, an open-risk list, and the evidence needed before quotation and commissioning.
One review path
Inputs → decisions → evidence
- Energy and power requirement
- Voltage and storage starting point
- Equipment compatibility risks
- Installation and commissioning inputs
- Remote support record
01 · System Design Brief
Start with the energy budget and the worst operating case.
A model name is the output of the first review, not the starting requirement.
Autonomy & recharge
Days without useful solar, seasonal solar window, generator or grid backup.
Existing equipment
Inverter/charger, MPPT, array configuration, protection and monitoring models.
Site & expansion
Space, structure, temperature, dust, moisture, altitude and future load growth.
02 · System Starting Points
Choose the architecture after the requirement is visible.
These are configurable discussion points for project review, not universal system recommendations or fixed production promises.
OV-B12-200
12.8V · 200Ah · 2560Wh for compact low-voltage requirements.
View product details →OV-B24-100
25.6V · 100Ah · 2560Wh for projects with a confirmed 24V architecture.
View product details →OV-B51-100T
51.2V · 100Ah · 5120Wh fixed-storage starting point.
View product details →OV-B51-200S
51.2V · 200Ah · 10240Wh vertical project baseline.
View product details →Portable backup and rapid-deployment route
Portable power is a separate operating model.
Use a portable station when mobility, fast setup or temporary backup matters more than a permanently installed battery bank. It is not presented as a substitute for a designed fixed 51.2V system.
03 · Compatibility & Commissioning
Lock the equipment combination before site work.
The approved configuration links the battery version, inverter/charger, MPPT, protection, wiring and commissioning record.
Compatibility matrix
- Battery-voltage and operating-window match
- Continuous and surge current path
- Charge set-points and low-temperature behavior
- Communication requirement and approved protocol
- Parallel/expansion rules for the exact production version
Commissioning pack
- Approved connection and protection schedule
- Project-confirmed settings sheet
- Polarity, isolation and pre-energization checks
- Initial charge/discharge and alarm checks
- Final configuration and handover record
04 · Remote Diagnostic & Support
Turn a field symptom into an evidence-based next step.
Remote support starts from the approved system record and the actual fault evidence—not a generic replacement promise.
Identify
Serial, batch, installed equipment, settings and recent system changes.
Capture
Photos, measurements, alarms, logs, load state and environmental conditions.
Isolate
Battery, charging, load, connection, configuration or environmental cause.
Resolve & record
Corrective action, responsibility path, parts and final project record.
05 · Documents & Evidence Status
Know what exists before committing to the project.
Evidence status follows the exact model, BMS, inverter integration, destination and ordered configuration.
System Design Brief
Template availableCaptures loads, autonomy, solar, equipment, site and expansion inputs.
Compatibility Matrix
Project-specificRecords supported, rejected and still-unconfirmed equipment combinations.
Commissioning Pack
Project-specificPrepared only after the exact electrical and mechanical configuration is approved.
Transport & Market Evidence
Version verification requiredReport and certificate identities must match the ordered version and destination.
Remote Support Record
Workflow availableConnects symptoms, evidence, diagnosis, action and responsibility.
