Error codes and troubleshooting
| Code | Meaning | What to do | Manual page |
|---|---|---|---|
| AC/Solar/Car charging high temperature protection | Charging input is too hot, so charging is protected. | After the product cools down, it will resume normal operation automatically. | 19 |
| AC/USB-C PD/DC output high temperature protection | The product is too hot while supplying AC, USB-C PD, or DC output, so that output is protected. | After the product cools down, re-press the AC/USB/DC power button. It will resume normal operation automatically. | 19 |
| AC/USB-C/USB-C PD/DC output overload protection | The load on an AC, USB-C, USB-C PD, or DC output exceeds the rated power, so that output is protected. | Remove the overloaded device and re-press the AC/USB/DC power button. It will resume normal operation automatically. Use electrical appliances within rated power. | 19 |
| Battery Failure | A battery alarm prompt appears on the LCD during use. It indicates a battery fault. | If the prompt appears and does not disappear after restarting, stop using the product immediately and contact Yoshino customer service. Call service if it persists. | 19 |
| Battery charging high temperature protection | The battery is too hot while charging, so charging is protected. Charging stops during the protection. | Charging can be resumed automatically after the battery cools down. Wait for the battery to cool. | 19 |
| Battery charging low temperature protection | The battery is too cold while charging, so charging is protected. | Charging can be resumed automatically after battery temperature rises above 0°C (32°F). | 19 |

FAQ
How long will the Yoshino B2000 SST run a refrigerator?
About 25 hours for a typical 120 W refrigerator that runs 35 % of the time, after inverter and depth-of-discharge losses.
Can the Yoshino B2000 SST start a sump pump or well pump?
Starting surge matters more than running watts: this unit is rated 2000 W output (no separate peak published). That is below a typical 1/2 HP sump pump start (about 2150 W); check your pump label. Use the calculator with your exact pump.
