As a premier Energy Storage Systems manufacturer, Balder Power is at the forefront of the global energy transition. We engineer and manufacture a complete portfolio of LiFePO4 (Lithium Iron Phosphate) battery solutions designed to maximize solar utilization, ensure power security, and reduce energy costs for clients worldwide.
Whether you are a solar distributor looking for residential backup batteries or an EPC contractor seeking turnkey commercial projects, Balder Power delivers scalable, safe, and efficient BESS solutions.
1. Residential Energy Storage: Power Your Home
Our residential line is designed for modern smart homes, focusing on aesthetics, ease of installation, and high compatibility with mainstream hybrid inverters (Deye, Victron, Growatt, etc.).
Diverse Form Factors:
Wall Mounted LiFePO4 Battery: Space-saving “Powerwall” style design (5kWh-10kWh).
Server Rack Battery: Standard 48V modules for scalable rack systems.
Stackable ESS (HV/LV): Modular “Lego-style” stacking for flexible capacity expansion (up to 80kWh+).
All-In-One Hybrid ESS: The ultimate plug-and-play cabinet integrating inverter and battery.
Key Benefits: reduce electricity bills through self-consumption and keep essential appliances running during blackouts.
2. Commercial & Industrial (C&I) BESS: Empower Your Business
For factories, commercial buildings, and microgrids, we offer robust Commercial BESS solutions ranging from 50kWh outdoor cabinets to MWh-scale containerized systems.
Advanced Thermal Management: Choose between cost-effective Air Cooling or premium Liquid Cooling technology for superior temperature uniformity and longer battery life.
Smart ROI Strategies: Our systems support Peak Shaving (discharging during expensive peak hours) and Demand Response, significantly lowering operational expenses.
Safety Assurance: Integrated with industrial-grade Fire Suppression Systems (Aerosol/Gas) and multi-level BMS protection.
Why Choose Balder Power ESS?
Grade A Cells Only: We exclusively use Tier-1 LiFePO4 prismatic cells (CATL, EVE, Gotion) to ensure 6000+ cycle life.
End-to-End OEM/ODM: From BMS customization and casing design to logo printing, we help you build your own local energy brand.
Global Certification: Our products are compliant with UN38.3, MSDS, CE, IEC62619, and UL standards for seamless import and distribution.
FAQs about Balder Power's Portable Power Stations
A: Unlike many competitors using NCM (Nickel Manganese Cobalt) batteries that last 800-1000 cycles, Balder Power exclusively uses LiFePO4 (Lithium Iron Phosphate) technology. Our systems are rated for 6,000 to 8,000 cycles at 80% Depth of Discharge (DOD). In real-world applications (one cycle per day), this translates to a service life of 15+ years, offering superior long-term ROI.
A: Absolutely. This is a common scenario. Our ESS solutions support AC-Coupling. This means if you (or your customer) already have a grid-tied PV system with a string inverter (like SMA or Fronius), you can add our battery system without replacing the existing inverter. The battery simply connects to the AC panel to store excess solar energy.
A: Standard grid-tied solar systems shut down during a blackout for safety (anti-islanding). However, when paired with our Hybrid ESS, the system creates a local microgrid. It automatically disconnects from the grid and keeps your solar panels operating, charging the batteries and powering your essential loads uninterruptedly.
A: For Residential use, a general rule is to cover evening consumption (typically 10kWh-20kWh). For Commercial (C&I) projects, sizing depends on the goal: Peak Shaving requires analyzing your load profile to shave the highest power spikes, while Backup requires calculating critical load runtime. Contact our engineering team for a free sizing calculation report.
A: Our LiFePO4 ESS solutions are virtually maintenance-free. Unlike lead-acid batteries that require watering, or diesel generators that need oil changes, our solid-state batteries only require basic visual inspection and keeping air intakes clear (for air-cooled models). The smart BMS automatically manages cell balancing and health monitoring.
