• This warranty is valid from 1st Jan 2024. (V1.5)

Special Point Out

Regarding HYBRID INSTALLATION

1. For Hybrid inverters installed with Triple Power batteries:
   • The default minimum capacity is 10% (can be changed to a higher level). During night time (no PV), when the battery is discharged to the minimum capacity, usually it will go into the “Idle mode” or “Standby mode”. However, the whole hybrid system is still consuming power. Therefore, you may see that the battery capacity sometimes goes down to low than 10%. When the battery capacity is down to 5% (protection level), it will trigger a charging demand, which requests charging from grid until it goes back to the normal minimum capacity level, it may happen in the night time or during winter time when there is no enough PV production or during bad weather days. This is a normal behaviour and won’t affect the battery life.
   • It is recommended to force charging battery from grid timely during bad weather (like continuous snowstorm, raining, cloudy days), so as to ensure that the battery won’t be fully discharged (0 capacity) under such situations. Besides, manually switching off the whole system is a good choice as well when under such conditions.
   • When adding a new extra battery to the existing system, it is requested that the new battery has the same capacity level with the existing battery system before it is added (pre-charge the original battery system and new battery to the full capacity, and then install them together), please check triple power battery user manual regarding this point;
   • When charging a battery from grid, consider its self-consumption during this process. The total energy taken from grid won’t be completely the same as the total energy discharged from the battery system. Hence, the warranty claim under such conditions will not be accepted.
2. For Hybrid inverters installed in completely off-grid settings:
   • It is requested that off-grid installation is inspected annually by a qualified electrician and recorded in form of documentation（See Table 2 for details）. Failure to comply with the described requirement to maintain the equipment may invalidate any warranty claims;
   • For better analysis and troubleshooting in case of a warranty claim, it is recommended that the customer register the inverter system online; otherwise, the customer will need to provide detailed information in Solax RMA form for the warranty claim;
   • The load installed with an off-grid system shall be calculated on the basis of its rated power; otherwise, it may have EPS Overload fault during night time or when there is not enough production from PV and battery, especially for inductive loads. Damages to inverters caused by incorrect installation will not be covered by the warranty.

*This Limited Warranty is a basic warranty promise from Solax to the end users. In certain countries/regions, end users may receive an additional warranty promise (should be at least equivalent to the manufacturer’s warranty) which is provided by Solax’s local distributors; should any claims arise in this respect, please direct them to the local distributor. Please note this limited warranty statement may NOT be the latest version, if any needs, please contact with Solax to get the latest version.

Feedback to the installer for handling

Is there any situation where the load cannot be carried

|  | If so, confirm whether EPS is connected to inductive loads with high starting current, such as water pumps, fixed frequency air conditioners, motors, etc. When this type of load is started, it may cause EPS overload. It is recommended

not to connect it to the EPS port

The battery is running normally|  | Feedback to the installer for handling
When connecting the Triple Power battery, it is recommended to set the min SOC of the battery to be higher than 10%|  | Due to off grid operation, if SOC ≤ min SOC, the inverter cannot enter EPS mode, and the battery needs to be charged to SOC of 31% to restore EPS

output

If the system is connected to lead-acid batteries, the NTC wiring should be firmly and reliably connected to the

battery
