Empowering Independence: The Off-Grid Energy Storage Revolution for Wholesalers and Installers

Mr. Harvey was struggling with quality in his BUSINESS. He has a brand of storage solutions for both on and off-grid application units. Most of his customers were complaining about QUALITY and PERFORMANCE. Our team understood their concerns, and we designed their supply chain. 

Starting with suppliers, we performed a complete audit of their current suppliers. Detailed background and quality check of an ON and OFF-grid solar generator supplier. Our team visited factories and filtered out low-quality suppliers. Then, we did supplier hunting for him to get the right quality. 

Our team standardized factories of a chosen OFF-grid energy storage manufacturer. We proposed three inspection services. One before mass production to ensure RIGHT RAW materials. Second, during Production, to get battery bank units on time. T

The last one after production is to filter out low-quality Solar battery systems. Inspection staff check the batteries’ function from off-grid power capacity. Tested their performance during power outages. 
As a result, his power company product started to last longer. Customers charge batteries effectively for more energy. It generates both REVENUE and RESPECT in the market.

    What is MOQ for logo printing?

    MOQ starts with one quantity to give you an idea for a trial. CUSTOMIZATION services start with ten sets. Use OEM and ODM services on both bulk and small inventory orders.

    How much life span of the solar generator?

    The cycle life is up to 5000+ at 80% DoD with an A-graded lifepo4 cell. On average, they last from 5 to 8 years with good maintenance. The lifecycle depends on the batteries’ function, too. 

    What is the order process?
