Market research in different countries and regions:
1. Indonesia (Archipelago Nation)
Background: With thousands of islands, grid unreliability is pervasive outside major cities. Solar adoption is rising for homes, telecom towers, and island resorts.
Findings:
Positioning: Primary solution for off-grid and poor-grid areas. The SBU (Solar-Battery-Utility) mode is highly valued.
Sales: Strong demand in Eastern Indonesia. Price competition is fierce, but reliability is the ultimate decider.
Service: Distributors insist on local stock of critical components. "Lithium Battery Activation by PV" was a standout feature for remote locations without stable grid access.
Tech Focus: High humidity and dust require robust build. The detachable dust cover was positively noted.
2. Philippines (Typhoon-Prone)
Background: Frequent typhoons cause prolonged power outages. Solar+battery systems are seen as essential for resilience.
Findings:
Positioning: Critical backup power and energy independence. Surge power (17,000VA/22,000VA) is a key selling point for starting pumps and tools post-storm.
Sales: Boom in residential and SME sectors. Instagram and Facebook are major discovery platforms.
Service: Demand for extended warranty (beyond standard). Installer training on correct grounding and anti-shock terminals is crucial.
Tech Focus: Fast transfer time (<20ms) is heavily marketed for protecting sensitive electronics.
3. Vietnam (Manufacturing Hub)
Background: Rapid economic growth strains the grid. Factories and farms seek to reduce operational costs and ensure production continuity.
Findings:
Positioning: Cost-saving and backup solution for small workshops and agricultural processing.
Sales: Driven by ROI calculations. The high peak efficiency (94%) directly appeals to cost-conscious business owners.
Service: Need for clear Vietnamese documentation. Support via Zalo is preferred.
Tech Focus: Capability to work without a battery ("Grid-tie like" operation with solar) generated significant interest for reducing payback period.
