Solar battery repair and diagnostics.
A battery that stops backing up the house is usually a fault to diagnose, not a unit to replace. We help you review battery service options, including fault assessment, warranty questions, and replacement planning where it is actually needed.
- Any battery brand, including systems installed by another company
- Backup, communication, and commissioning faults reviewed before replacement
- Warranty route and remaining coverage confirmed in writing
Tell us about the battery
Brand, what the system is doing, and your ZIP code are enough to start. Equipment details can follow.
A battery that stops backing up the house is usually a fault to diagnose, not a unit to replace. Palm Beach Solar helps you review battery service options, including fault assessment, warranty questions, and replacement planning where it is actually needed.
Start with the behavior, not the brand
Collect information from your app, documents, and safely accessible labels. Stay off the roof and leave electrical covers, conduit, connectors, and wiring to qualified professionals. Keep clear of damaged, hot, swollen, or wet equipment. For smoke, fire, burning smell, or an immediate electrical hazard, move to a safe location and contact emergency services.
Record what the system actually did: did the house lose power during an outage, did the app stop reporting, did the battery stop charging, did a breaker trip, or did the unit make an unfamiliar noise. Note when it started and whether it followed a utility outage, a firmware update, a router change, a roof project, or a storm.
Each of those points toward a different assessment. A battery that reports normally but will not carry the house has a power-path or configuration problem. A battery that carries the house but disappeared from the app has a communication problem. Treating either one as proof of a failed unit leads to replacing hardware that was never the problem.
What the assessment should establish
The service provider should separate a reporting issue from a backup-performance issue and review the relevant electrical and configuration conditions. A replacement recommendation should explain the diagnosed fault, the available warranty route, and compatibility with the existing system.
Ask for the finding in writing before authorizing equipment. A recommendation to replace a battery without a stated cause is a guess with an invoice attached, and it is the most common thing we see when a second opinion is requested on a battery.
Battery repair needs a compatibility review
Replacement equipment must fit the system design. The review can include the inverter, gateway and monitoring platform, rapid-shutdown equipment, existing solar pairing, backup-circuit assignment, wiring, and utility requirements. Equipment selection and commissioning belong in the written scope.
Older systems are where this matters most. A modern battery may be physically compatible and electrically incompatible, or may require a monitoring platform change that affects how the array reports and how backup loads are managed.
Compare complete costs, not unit prices
Ask which parts are covered, who handles manufacturer authorization, and how labor, shipping, diagnostic time, removal, reinstallation, and testing are billed. Keep the fault report and the service record with your system documents.
A warranty-supplied battery is not a free repair. The unit arrives at no cost and the labor to diagnose, remove, replace, commission, and test it is usually the owner's responsibility, which is why the two numbers need to be compared separately.
What battery service typically costs
These are planning ranges for standard residential work, not a quote. The service partner diagnoses the system on site and quotes the actual repair in writing before any work begins.
| What is wrong | Typical range | What the work involves |
|---|---|---|
| What is wrongDiagnostic visit (credited toward the repair) | Typical range$150 to $300 | What the work involvesMonitoring review, inverter codes, connections, and a written finding |
| What is wrongMicroinverter or optimizer replacement | Typical range$250 to $600 per unit | What the work involvesPart plus roof access; units are usually replaced one at a time |
| What is wrongString inverter replacement (all-in) | Typical range$800 to $1,200 | What the work involvesUnit, labor, permit, and re-commissioning for a standard single-inverter residential system |
| What is wrongMonitoring or communications repair | Typical range$150 to $450 | What the work involvesRestores production reporting; does not always require roof access |
| What is wrongRoof leak at a penetration or flashing | Typical range$400 to $1,200 | What the work involvesRoof scope; may require removing and reinstalling the affected panels |
| What is wrongBattery communication or gateway fault | Typical range$150 to $450 | What the work involvesRestores reporting and app visibility; often no equipment replacement |
| What is wrongBattery unit replacement (all-in, standard residential) | Typical rangeQuoted per system | What the work involvesUnit, labor, commissioning, and backup testing; depends on brand, capacity, and warranty coverage |
- A service call runs $150 to $300 and is credited toward the repair if you proceed.
- Main-panel or wiring upgrades, trenching, multi-story or steep access, damaged racking, permit-required work, and systems installed by a defunct contractor move a project above these bands.
- Battery replacement is quoted per system rather than published as a band, because capacity, brand, and whether the manufacturer supplies the unit under warranty move the number too far to state honestly as one range.
Repair or replace: what decides it
The decision follows the diagnosed fault and the condition of everything the battery connects to, not the age of the unit alone.
| Situation | Usually points toward | What to confirm first |
|---|---|---|
| SituationBattery missing from the app, backup still works | Usually points towardCommunication or gateway repair | What to confirm firstWhether backup operation is verifiably normal during a test |
| SituationBattery full but house loses power in an outage | Usually points towardConfiguration, backup-circuit, or transfer review | What to confirm firstWhich circuits are assigned to backup and the unit's output rating |
| SituationBattery will not charge above a partial level | Usually points towardCell, firmware, or warranty assessment | What to confirm firstWarranty status and whether the manufacturer requires its own diagnostics |
| SituationBreaker trips repeatedly on the battery circuit | Usually points towardRoot-cause electrical assessment before any reset | What to confirm firstThat the fault is established in writing before equipment is ordered |
| SituationUnit failed within warranty | Usually points towardWarranty claim plus owner-paid labor | What to confirm firstWho files the claim and which charges the warranty excludes |
- Any recommendation to replace the battery rather than repair it should explain why the existing unit cannot be retained.

What Sets Us Apart
Separate the reporting fault from the backup fault
A battery that vanished from the app and a battery that will not carry the house during an outage look similar on a phone and are completely different problems. One is a communication path, the other is a power path, and they lead to different scopes and different costs.
Backup behavior checked against the actual loads
A full battery can still fail to hold the house if the backup circuits are assigned wrong or a single load exceeds the unit's output rating. That is configuration, and it is far cheaper to correct than equipment.
Warranty route confirmed before work is ordered
Battery warranties commonly run ten years or more and typically cover the unit while leaving labor, shipping, diagnostic time, and removal to the owner. Knowing which side of that line a repair falls on changes the decision, so it is established in writing first.
Any brand, and any original installer
Requests are reviewed for every battery brand and for systems installed by a company that is no longer operating. The manufacturer still stands behind the equipment even when the installer does not.
Compatibility reviewed before replacement
A replacement battery must fit the existing inverter, gateway, monitoring platform, rapid-shutdown equipment, and utility requirements. A unit that fits the wall but not the system is not a repair.
Written scope with the verification method included
The scope should say what was tested, what the finding was, and how backup operation will be confirmed afterward. That last part is what separates a completed repair from a bill.
How It Works
Send what the system is doing
Share the battery brand, the model if it is safely readable, the exact alert or behavior, when it started, and your city or ZIP code. A screenshot from the monitoring app helps more than a description.
Records, history, and warranty reviewed
The partner reviews monitoring history, commissioning records, equipment age, and warranty status to determine whether the condition is a known fault, a warranty matter, or site-specific.
Diagnosis and written finding
The assessment separates communication from backup performance, checks the relevant electrical and configuration conditions, and documents the finding along with the recommended scope.
Repair, replacement, and verification
Work proceeds under a written scope that identifies the provider, charges, and warranty terms. Backup operation is tested afterward so the repair is confirmed rather than assumed.
Frequently Asked Questions
Usually not, and that is the first thing the assessment has to establish. A battery that stops carrying the house is more often a communication or commissioning fault, a tripped breaker, a backup-mode or settings change, a firmware issue, or a failed component than a dead unit. Replacement is a conclusion, not a starting point.
