1. Check if there are some inductive load on the output, if this fault appears at the
startup,it caused by shock current of load, you need reduce the load and resrtart
inverter.
2. Reduce the connected load by switching off some equipment.
4. 8 Error 08
Fault description: Bus voltage is too high
Analysis：
1. DC-DC diode or driver circuit is damaged.
2. Battery can’t build communication with inverter.
Suggestion:
1. Turn off PV, batteries and grid to power off the inverter completely till there is nothing
displayed on LCD and restart, observe whether the error code is cleaned.
2. please arrange to upgrade inverter software using ISP tool program software.
inverter new firmware software version：F2809_GW500.07_20191227_B.
3. If fault still exist after upgrading software or it’s not convenient to upgrade software ，
please change some settings below：
program 02：40A
program 05：USE
program 19：52V
program 20：51V
If it’s still not work，please also try to set lower settings for it：
program 02：30A
program 05：USE
program 19：51.5V
program 20：51V
4. For lithium icon battery，strongly suggest try to upgrade software，US2 is especially
designed for lithium icon batteries that can’t build communication with inverter.USE is
designed for lead acid batteries.this is also the difference between USE and US2.
5. Please check your pv panels configuration ， for SPF5000TL HVM model ： suggest
connect with 12 pcs（330W），3 in series，4 parallel.
4. 9 Error 09
Fault description: Bus soft start failed.
Analysis：
1. Battery mode setting wrong.
2. The inverter diode or the IGBT on the high voltage side of DC/DC is damaged.
