LPBR24150-P

Step-by-step troubleshooting checklist

1. 1.Note the exact code and timing

   Write down the exact code shown on the display, what the unit was doing when it appeared (charging, discharging, idle, grid-tied), and any LEDs or audible alarms. The same code can have different fixes depending on context.

2. 2.Check the recommended fix on this page

   Find the code in the list below and read the cause + recommended fix. Most warning-level codes can be cleared by following the listed action — usually reducing load, checking wiring, or restarting the unit.

3. 3.Verify the source manual page

   Each code shows the source manual filename and page number. Open that exact page in the official manual to verify model-specific notes (firmware version, parallel-config notes, regional variants) before acting.

4. 4.Disconnect AC, DC, and battery before opening

   If a fix requires opening the enclosure or accessing terminals, disconnect AC input, DC PV, and battery in that order. Wait at least 60 seconds for capacitors to discharge before touching any conductors.

5. 5.Escalate critical codes to authorized service

   Critical codes (short-circuit, IGBT failure, BMS hardware error) should not be cleared by end users. Note the code, model number, and source manual page, then contact an authorized service partner.

Common questions about LPBR24150-P error codes

Where can I find the official Felicity LPBR24150-P error code manual?

Each code on this page lists the official source manual filename and page number at the bottom. The manuals are published by Felicity on their website; we compile the codes here so you can search across all of them at once instead of opening each PDF.

Is the LPBR24150-P the same as other Felicity models?

Some Felicity units share firmware across a family of variants — the same fault codes apply to multiple model numbers. Look at the "also covers" chips below the title to see which other model numbers this page applies to.

What's the most critical code on a Felicity LPBR24150-P?

Critical-severity codes (red dot) are the ones that trip the unit offline immediately — typically short-circuit, IGBT, or BMS hardware failures. These are listed first when you filter by severity. Do not bypass them; they indicate a hardware or safety condition that requires service.
