What do I do when error code 217 occurs?

Error code 217 indicates that something with the battery is not quite right. This usually does not imply a serious issue, but a visit to the site may be necessary.

For ARK Battery:

Measure the voltage in each battery and check the voltage. The voltage should be between 48-54V, with no more than a 0.5V difference between batteries.

If the voltage is between 32-47.9V, the batteries will need to be support-charged using a separate DC power supply capable of delivering 51V (DC) and 5-8A. Charge all batteries to 52V and start the system. After this, the problem should be resolved.

If the voltage is below 32V, the batteries need to be replaced. Please contact our Growatt Support at growatt@aprilice.se with pictures and information about the case for further help (including serial number, order number, and installer code).

For APX Battery:

If error code 217 appears on APX or if the APX battery is not visible on the OSS platform, please check the manual where description of issues for APX contains. If the manual does not resolve the problem, please check the MCS version and software of the battery & Power module (Version 15 & 18 are recommended).

If the version is lower than version 15 or different between the Control Module (98034-P2) & the battery (APX 5.0P-B1), various problems may occur. It is recommended to update all components via Growatt or on-site using an update file and a USB stick. Please contact our Growatt support at growatt@aprilice.se for instructions.
