Introduction

Solax Triple Power Batteries (hereinafter "T-BAT") are manufactured by SolaX Power Network Technology (Zhejiang) Co., Ltd. (hereinafter referred to as Solax). Solax provides the following limited warranty ("Warranty") to distributors/installers ("Buyer") through Authorized Resellers. This Warranty is applicable for the following battery modules and BMS units: T58, T30, TP-HS25, TP-HS36, TP-HR25, TP-HR36 battery module and T30-BMS, TBMS-MCS0800, TBMS-MCR0800, as listed in Table 1. These products must have been sold and installed from January 1, 2023.

The applicable battery models include: T-BAT H 5.8/HV11550/MC0600/HV10230/MCS0800/MCR0800/TP-HS25/TP-HS36/TP-HR25/TP-HR36 Battery.

1. Purpose

The primary purpose of this warranty is to clearly define the matters related to the warranty policy of Solax products.

2. Warranty Condition

2.1. Warranty Period

The performance warranty for the products is valid for 120 months from the date the battery is commissioned by the installer, or 6 months after the manufacture date, whichever comes first. This warranty does not cover any accessories or tool kit items provided with the product.

2.2. Warranty Limitation

Seller's liability under this warranty is limited to replacement, repair, and compensation. Replaced or repaired products will be warranted for the remainder of the original warranty term.

2.3. Exclusive of Warranty

No warranty claims will be acknowledged or accepted for damages related to the following causes. Claims related to defects caused by these factors are not covered by Solax Triple Power's warranty obligations:

• a) Force majeure (e.g., storm damage, lightning strike, overvoltage, fire, thunderstorm, flooding).
• b) Improper or noncompliant use.
• c) Improper installation, commissioning, start-up, or operation (contrary to the guidance in the installation manual supplied with each product).
• d) Inadequate ventilation and circulation resulting in minimized cooling and natural air flow.
• e) Installation in a corrosive environment.
• f) Damage during transportation.
• g) Unauthorized repair attempts.
• h) Failure to adequately maintain the equipment. An on-site inspection by a suitably qualified technician is required following sixty months of continuous use. Warranty claims made beyond 60 months from the commissioning date may be declined if adequate maintenance cannot be demonstrated.
• i) External influence including unusual physical or electrical stress (e.g., power failure surges, inrush current).
• j) Use of an incompatible inverter or devices.

For products damaged due to reasons not attributable to the seller, Solax Power will provide charged services. All expenses, including material cost, labor cost, warehouse cost, transportation cost, customs duties, analysis cost, management cost, corporate profits, and disposal expenses, will not be covered by Solax Power.

3. Performance Warranty

Solax warrants that the product retains at least 70% of its Nominal Energy for either 120 months after the commissioning date or for a minimum Energy Throughput as specified in the table below (whichever comes first), provided the battery system is operated under normal use according to Solax's specifications and manual. The product's Depth of Discharge (DoD) is 90%, and it can operate safely within this DoD range during the warranty period.

The term "Nominal Energy" refers to the initially rated capacity of the product as indicated on its label.

Precondition for warranty: The ambient temperature during battery operation must not be outside the following ranges:

• T-BAT H 5.8/HV11500: between -10°C and 50°C.
• HV10230: between -30°C (with heating function) / -10°C (without heating function) and 50°C.

The energy throughput must be within the values indicated in the table below:

For Capacity measurement conditions, see details below:

4. Product Warranty

Solax Power warrants that T-BAT will be free of defects caused by improper design, workmanship, or defective materials. The warranty is valid for 120 months from the date the battery is commissioned by the installer or 6 months after the manufacture date (whichever comes first). After the warranty period, Solax Power has no obligation to provide spare parts or batteries.

5. Extend Additional Batteries

It is possible to add extra batteries to an existing system within 1 year after installation. Before extending the system, an electrician must follow every step on the Battery Extension SOP provided by Solax Power to ensure the batteries are at the same voltage level. Warranty information can be added during the warranty registration process on the website.

6. Warranty Registration

All batteries must be registered for warranty to qualify under the Exchange Program. Suppliers/installers must provide the end-user with the relevant warranty registration certificate. The end-user (or installer on behalf of the customer) must register the warranty on the Solax website to receive a full warranty certificate. Warranties must be registered no more than six weeks following the date of commissioning.

Information required for registration:

• a. Inverter model
• b. Inverter serial number
• c. Battery serial number
• d. Installation date
• e. Customer name
• f. Full installation address
• g. Purchase receipt

For extended warranties, after receiving the warranty certificate by email, it is necessary to access the monitoring website to complete the warranty extension and payment online. Upon receipt of the registration request, the end-user will receive a full warranty certificate by email within seven working days.

7. About Service
