Retrofit and repower an ageing solar, inverter or battery system
Preserve sound switchgear, cabling, PV, generators and metering where evidence supports reuse; isolate obsolete or insecure dependencies; then redesign control, protection, documentation and acceptance around the owner’s present duty.
SOLAR + BESSLegacy solar and battery retrofitPhilippinesFree initial review
01
When this matters
The original installer is unavailable, parts are obsolete, drawings and settings are incomplete, cloud access is uncertain, or the site has changed loads and operating priorities since commissioning.
The decision crosses operating, electrical, commercial or regulatory boundaries.
Management needs a defensible next step before committing capital.
02
What we evaluate
We rebuild the as-operated single-line, equipment and firmware register, settings backup, failure history, protection interfaces, battery compatibility, data flows, bypass path and safe-isolation procedure before deciding what can remain.
Available bills, interval data, drawings, settings, contracts and operating records.
Assumptions, contradictions, missing evidence and the party responsible for each dependency.
03
What you receive
A keep / repair / isolate / replace matrix, staged retrofit design, downtime and rollback plan, cyber and data boundary, updated operator documentation, and acceptance tests for normal and degraded operating states.
A decision memo that separates verified facts from assumptions.
Prioritized actions, owners and acceptance evidence for the next stage.
A controlled path from question to evidence
Question → evidence → decision → acceptance
Every scope states what is known, what remains open, who owns the dependency and how the result will be verified.
