Part 1: Core Cell and Battery Pack<\/a> Certification \u2013 TISI Mandatory Certification<\/h4>\n\n\n\n

Thailand enforces a strict mandatory certification system for battery products. To sell residential storage products<\/strong><\/a> legally, manufacturers must first obtain TISI certification.<\/p>\n\n\n\n

1. Applicable Standards<\/h5>\n\n\n\n

Currently, the old standard TIS 2217\u20112548<\/strong> (equivalent to the old IEC 62133) remains in force.<\/p>\n\n\n\n

However, Thailand has already published the new standards \u2013 TIS 62133\u20111:2565 and TIS 62133\u20112:2565<\/strong>, which correspond to IEC 62133\u20111\/2. Although the enforcement date for these new standards has been postponed, we strongly recommend switching to them as soon as possible. They will become mandatory in the future.<\/p>\n\n\n\n

<\/p>\n\n\n\n

2. Key Certification Restrictions \u2013 Points of Particular Concern for Residential Storage Manufacturers<\/h5>\n\n\n\n

Certificate holder must be a locally registered entity in Thailand.<\/strong><\/p>\n\n\n\n

Foreign manufacturers cannot directly hold a TISI certificate. Instead, they must appoint a Thai subsidiary, a partner importer, or a local agent to act as the certificate holder.<\/p>\n\n\n\n

Factory audit required.<\/strong><\/p>\n\n\n\n

When applying for the first time, TISI or its authorized representatives will conduct an on-site factory audit at the manufacturer’s facility in China. During this audit, they examine the quality management system. Although ISO 9001 certification can partially streamline the process, document review and sample testing remain rigorous.<\/p>\n\n\n\n

Mandatory dual-labeling with QR code.<\/strong><\/p>\n\n\n\n

Before leaving the factory, products must bear the TISI safety mark with a QR code. When scanned, the code must direct users to the electronic license page in the TISI official database.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Part 2: Grid-Connection Certification \u2013 Approval Requirements from the Three Power Authorities (MEA\/PEA\/EGAT)<\/h4>\n\n\n\n

For residential storage systems \u2013 especially AC-coupled or hybrid inverter all-in-one units \u2013 grid connection requires approval from the relevant regional power authority. Moreover, the product models must appear on the authority’s inverter\/ESS approved list (whitelist).<\/p>\n\n\n\n
