SERVICES
Solar, Inverter & Electrical Solutions
Choose the problem you need solved. Each service is built around the actual electrical and operating limits of the system.
Inverter Repair & Diagnostics
Engineering-first inverter diagnosis for error codes, charging faults, no-output faults, cooling problems, power-stage failures, MPPT issues, and control-power problems.
VIEW SERVICESolar System Maintenance
Preventive inspection of panels, wiring, protection, inverter cooling, batteries, settings, and system performance.
VIEW SERVICEBattery Systems & Storage
Lithium and lead-acid battery sizing, protection, current-limit checks, inverter settings, BMS communication, and backup optimization.
VIEW SERVICEElectrical Troubleshooting
Systematic troubleshooting for breaker trips, overheating, wiring faults, load problems, protection issues, and abnormal power behavior.
VIEW SERVICESolar System Upgrades
Upgrade existing solar and backup systems with additional PV, improved battery storage, safer protection, better configuration, or capacity changes.
VIEW SERVICEOUR STANDARD
Engineering First. Clear Decisions.
Measure Before Guessing
Symptoms are traced to the failed function before parts are replaced.
Respect Electrical Limits
Voltage, current, thermal, MPPT, battery, cable, and protection limits guide the solution.
Repair When It Makes Sense
A repair is recommended only when it can be done safely and economically.
Explain the Work
Customers should understand the fault, the work performed, and the important operating limits.
THE METHOD
How DABAJA Approaches a Job
A repeatable process reduces guesswork and makes the recommendation easier to explain.
01
Consultation
We understand the actual problem, load, equipment, priorities, and budget before recommending work.
02
Inspection & Diagnosis
We inspect the relevant system blocks, wiring, protection, batteries, inverter behavior, and available measurements.
03
Engineering Decision
We explain what we found and recommend a repair, upgrade, or replacement only when it makes technical and economic sense.
04
Repair or Installation
Work is carried out cleanly with attention to electrical limits, protection, cooling, configuration, and serviceability.
05
Testing & Handover
The result is checked under controlled conditions and the important settings, limits, and observations are explained clearly.
06
Follow-Up
Maintenance and follow-up are available when the system needs monitoring, adjustment, or future expansion.
WHAT WE SOLVE
Typical Solutions & Engineering Scenarios
These are examples of the types of work DABAJA handles. Real customer case studies will be added only when documented and approved.
SOLAR DESIGN
Residential Solar System
Load-based sizing, PV string design, inverter and battery selection, protection, cabling, and commissioning.
DIAGNOSTICS
Inverter Fault Diagnosis
Structured checks for no-output, charging, cooling, power-stage, driver, SMPS, sensing, and communication faults.
STORAGE
Battery Backup Upgrade
Usable-energy sizing, current-limit checks, lithium/BMS compatibility, cabling, protection, and inverter settings.
ELECTRICAL
Electrical Fault Isolation
Breaker trips, overheating, voltage drop, wiring faults, protection issues, and inverter/load interaction.
CORE SPECIALTY
Inverter Diagnostics & Repair
A fault code points to a symptom. Diagnosis determines which function actually failed.
Internal work may involve high DC voltages and stored energy. DABAJA's customer-facing guidance focuses on safe information gathering; board-level diagnosis is performed with appropriate isolation, discharge, measurement, and controlled testing.
