Battery overvoltage

Battery overvoltage is reported by the battery or hybrid inverter as a warning or error code when the battery voltage is too high, sometimes only for a short time. On SMA Sunny Island units it shows as warning W210 (BatVtgHiWarn) or as F208 and W209 battery overvoltage errors. If the code arrives over SiCom (F921 or W937), the external battery management system detected the overvoltage, so fix the cause there using the battery manufacturer's documentation. On SMA W210, the corrective measure refers to the country data set configured for stand-alone grid operation, so check that setting. Solis hybrid inverters report a hardware-level battery overvoltage as OV-Vbatt-H. For OV-Vbatt-H, first check whether the battery breaker or fuses in the battery input circuit have tripped, then check the battery for damage, and restart the inverter.

<!-- review notes

• sentence 4: support check: partial - The corrective measure fragment mentions the country data set for stand-alone grid operation, but the text is truncated and does not say to check that setting.
• sentence 5: support check: partial - OV-Vbatt-H is a battery overvoltage hardware failure/fault, but the passages don't name hybrid inverters specifically; Solis is implied by the message names.
• sentence 6: support check: partial - The passages give breaker/fuse check, battery damage check and restart, but the order is partly from different rows and restart appears only in the u8/u11 rows, not alongside the damage check.
• sentence 4: review: partial - The W210 corrective-measure text is cut off and mentions only the country data set for stand-alone grid operation, so the instruction to check that setting is inferred rather than stated. -->
