Solar Battery Storage Solutions for Installation Companies

sun.store is a professional B2B marketplace built for PV installers and contractors. Here you compare in-stock solar battery storage options from multiple suppliers in one place, see transparent availability, and select the configuration that matches your inverter lineup and project timelines. Listings are structured for pro buyers: clear usable capacity, voltage class, communication protocols, cycle life, and warranty terms—so you can specify fast and order with confidence.

For pricing, you view supplier offers side by side, request project-level quotes, and lock in conditions suitable for your purchasing cadence. Documentation—datasheets, manuals, and certifications—comes consolidated at product level to support design approvals and client handover packs. Logistics are streamlined with pallet and, where applicable, container options plus delivery coordination windows to the site or warehouse.

Whether you deliver residential upgrades or small commercial and industrial (C&I) systems, the marketplace helps you source solar batteries that align with your PV architectures: from single-phase hybrid retrofits to three-phase storage plants with higher power requirements and longer runtimes.

Types of Solar Batteries

Selecting the right battery for PV system work starts with cell chemistry and system voltage. Below are the core categories you’ll see across solar batteries for sale on sun.store, with practical context on when each fits.

LFP (LiFePO₄) Batteries

LFP (LiFePO₄) is the default choice for many installers due to its robust thermal behavior and strong cycle life. Compared to NMC (nickel manganese cobalt), LFP typically offers higher safety margins and flatter voltage curves under load, which supports predictable SOC estimation. In residential solar battery storage, LFP is favored for daily cycling, backup power, and dynamic tariff shifting. In C&I environments, LFP’s cycle throughput and lower degradation rate make it suitable for peak shaving and time-of-use strategies. If you need maximum energy density within tight space, NMC can be lighter per kWh, but LFP is usually the safer bet for broad deployment.

Low-Voltage Batteries

Low-voltage batteries generally operate in the 48–60 V class and integrate well with many legacy hybrid inverters and off-grid chargers common in retrofit markets. They are forgiving for installers familiar with DC cabling and offer straightforward serviceability. Pros: wide inverter compatibility, easier field diagnostics, and modular stacking at manageable current levels. Cons: higher DC currents for the same power can mean thicker cables and shorter allowable cable runs. For retrofits or small single-phase solar battery system additions, low-voltage is often the fast path to reliable battery backup for home and light commercial use.

High-Voltage Batteries

High-voltage batteries (typically 200–600 V systems) reduce current for the same power output, enabling thinner cables, smaller conduit, and improved round-trip efficiency in larger installations. They pair well with modern three-phase hybrid inverters and are common in C&I and high-demand residential segments. Benefits include better inverter efficiency at power, longer cable distances, and clean integration with high-power PV/hybrid stacks. Note commissioning: vendor-approved sequence (stack order, address DIP, CAN termination) is critical to avoid BMS faults.

Modular and Stackable Battery Systems

Modular and stackable battery platforms let you scale in defined kWh steps—ideal for phased upgrades or evolving load profiles. You can begin with a base cabinet or wall-mounted pack and add modules as the client adopts EV charging, heat pumps, or expands operating hours. Cabinet systems centralize DC protection and BMS access; wall-mounts minimize footprint where space is tight. Commissioning notes: match module firmware, observe manufacturer SOC equalization steps, and document serials for warranty registration and asset tracking.

Key Features That Set Solar Batteries Apart

Cell chemistry (LFP vs. NMC): LFP prioritizes safety and stable thermal behavior; NMC offers higher energy density. Consider temperature performance, enclosure constraints, and client risk policy.

Cycle life & warranty: Look for throughput (MWh/kWh) and year coverage (often 5–10+ years). Check conditions: operating temperature bands, DoD limits (e.g., 90–95%), update requirements, and charge/discharge rates.

Usable capacity & round-trip efficiency: “Usable” excludes top/bottom buffers controlled by the BMS; typical efficiency ranges 90–96% depending on voltage class and temperature—key for ROI modeling.

Scalability: Modular/stackable growth, parallel cabinets, and DC- or AC-coupled expansion. Confirm max strings, module addressing rules, and allowed parallel counts.

Safety & protections: Integrated BMS with cell-level monitoring, overcurrent/overvoltage, short-circuit and thermal management, contactor control, and fault logging.

Environmental robustness: IP ratings for indoor/outdoor, clear ambient operating ranges, altitude derating, and condensation guidance. Ensure mounting surfaces meet load and ventilation requirements.

Integration: Hybrid/on-grid inverter compatibility lists, supported communication buses (CAN/RS485), firmware update paths, and monitoring portals. Validate grid-code profiles when required.

Installation practicality: Pre-wired bases, accessible fusing, front service access, lifting/moving instructions, and serial capture for warranty and asset systems.

Commissioning & service: App or local HMI tools, SOC calibration steps, equalization routines, event logs, and remote diagnostics availability.

Battery Applications for Residential and Commercial Projects

Residential (single-phase and three-phase):
- Self-consumption boost and battery backup for home critical loads with clear ATS/backup wiring.
- Off-grid or weak-grid operation using solar energy battery plus generator integration.
- Dynamic tariffs/time-of-use load shifting; pair with EV charging to shave evening peaks.
- Typical sizing: start 5–10 kWh and scale by module as load profile evolves; ensure hybrid inverter is on the approved compatibility list.

Commercial/C&I:
- Peak shaving and time-of-use arbitrage; size for target kW reduction and required kWh depth.
- Demand response and load management (where programs are available); confirm site metering and control interfaces.
