01 — Who we are
A supplier built around one market: Europe
One hundred percent of our export revenue comes from Europe — a market that does not forgive weak cells, missing documents or late shipments.
INSUM Energy is the export arm of Yinsheng New Energy Technology Co., Ltd. — a Shenzhen manufacturer integrating R&D, production, sales and service of solar lithium battery storage systems.
Founded in 2020, we source, configure and ship LiFePO4 storage for distributors, installers and system integrators. A team of 11–50 specialists covers cell sourcing, BMS protocol matching for CAN, RS485 and Bluetooth, and export documentation.
That means one person carries your order from quotation to container. No handovers between departments, no re-explaining your specification at every step.
Our product range spans wall-mounted, vertical-style, stackable and high-voltage lithium batteries, small-scale C&I storage systems, and our own BMS technology — all built on 3.2 V 280 Ah / 314 Ah A-grade cells in 1P16S configuration.
We do not chase every market. Knowing one market deeply — its certifications, its grid codes, its installation habits — is why our buyers come back.
“We would rather be the obvious choice in 27 countries than an anonymous option in 170.”

The questions buyers ask first
If your question is not here, the fastest route is WhatsApp — we usually answer within two working hours.
What is your minimum order quantity (MOQ)?
For standard LiFePO4 cells, our MOQ is only 4 cells (one box). For DIY kits and accessories, MOQ is 1 set for any in-stock home energy storage model, including the 16 kWh, 51.2 V, 314 Ah DIY kit. Custom logo and enclosure graphics start at 100 sets, while capacity, voltage and BMS protocol can be configured from a single unit — so you can test one system before a full container order.
Do you ship to all EU countries?
Yes. We ship from our two EU warehouses in Poland to all 27 EU member states. Standard delivery is 2–5 working days, and all EU shipments are DDP — no customs fees or unexpected extra costs. Orders for other regions ship from Shenzhen.
What certifications do your products have?
Every unit is CE certified. UN38.3 and MSDS transport documents are issued for every shipment, and TÜV-tested components are available on request. We use Grade A LiFePO4 cells rated for 8,000 cycles at 80% DoD. All packs are tested before shipment and covered by a 5-year warranty.
Can I get a custom battery pack?
Yes. We offer full OEM and ODM service, from logo printing and enclosure design to BMS firmware configuration. Logo customization requires a minimum of 100 sets; sample production takes 7–15 days, and private-label packaging artwork is confirmed within 5 working days after receiving your files.
What warranty do you offer?
All products carry a 5-year warranty against manufacturing defects, including free spare parts and online technical support. Our service team replies within 2 hours on working days, and remote BMS diagnostics resolve most faults without returning hardware. Out-of-warranty spare-part quotes are provided within one working day.
