51.2V 200Ah Wall Mounted Battery with CAN RS485 for Solar Integrators

A Battery Selected Around Inverter Compatibility and DC System Design

This 51.2V 200Ah wall mounted battery is intended for solar installers, distributors and system integrators that need a clearly defined low-voltage battery platform for compatible hybrid or off-grid inverters.

Its key integration values include a 40.0–58.4Vdc operating range, 56.0V floating-charge setting, 100A continuous charging limit and 200A continuous discharge limit. These values should be checked against the inverter before communication features or mechanical installation are considered.

Optional CAN and RS485 interfaces can support battery-to-inverter data exchange when the communication protocol, cable pin definition and software settings are compatible. The existence of a CAN or RS485 port alone does not guarantee successful communication.

Four Checks Before Approving the Battery for a Project

Understand the 300A Pulse Rating Correctly

The battery has a listed pulse-discharge capability of 300A for one second. This value is intended for brief current demand and must not be used as the continuous operating current.

Continuous DC cables, busbars, terminals, fuses and breakers should be selected from the 200A continuous rating and the applicable installation conditions. The one-second pulse value should not be used to justify undersized conductors or protective devices.

The M8 battery connection must be assembled with suitable lugs and correctly sized conductors. Cable length should be kept practical, and positive and negative conductors should be planned to minimize unnecessary voltage drop.

Communication Is an Optional Project Configuration

Optional CAN and RS485 interfaces may allow the inverter to receive supported battery information such as operating status, alarms or state-of-charge data. The exact data exchanged depends on the selected protocol and equipment configuration.

When protocol compatibility has not been confirmed, installers should not assume that automatic charge-current control or battery-status reporting will be available. Electrical settings must still remain within the battery limits.

Installer-Oriented Specification Matrix

Solar Integrator FAQ

What inverter information is required for compatibility checking?

Provide the inverter brand, exact model, firmware version, battery-voltage range, charging-current limit and supported CAN or RS485 protocol.

Are CAN and RS485 guaranteed to work with every inverter?

No. Port type, protocol, cable pin definition and software configuration must all be compatible.

Should cables be sized for 300A?

Continuous system components should be selected according to the 200A continuous rating and applicable installation requirements. The 300A value lasts only one second.

What happens when communication is unavailable?

The installer must configure compatible voltage and current settings manually and should not assume automatic data exchange or charging control.

What must be checked before wall mounting?

Check the wall structure, fixing hardware, battery weight, cable route, service access, ventilation clearance and indoor environmental conditions.

Pre-Order Inverter Compatibility Review

A compatibility review can help confirm the voltage window, charge-current setting, communication protocol, cable definition and optional interface configuration before production.
