Also Known As

This pack is the same hardware sold under several equivalent labels: 51.2V 100Ah
(16-cell series nominal voltage), 48V 100Ah (the 48V system-voltage convention used by most
inverters and chargers) and 5.12 kWh / 5120Wh (the same pack expressed as energy).
System energy is stated at the cabinet level; the 100 Ah figure is the per-module rating.

Compatibility & Communication

Cabinets ship with an EMS supporting peak-shaving, self-consumption and remote O&M, and communicate over CAN bus, RS485 and RS232 (select models).

Compatibility is listed for communication-protocol matching only. It is not an endorsement or a
certified-partnership claim. Send us your inverter or charger model and we will verify protocol
matching before shipment.

What is the production lead time?

Lead time depends on the product: standard battery packs are typically 15-25 days, while larger integrated systems such as our mobile EV charging units are 35-45 days. The exact schedule is confirmed in your quotation.

Which battery cells does CMX Battery use?

The company has strategic cooperation agreements with top manufacturers like EVE and REPT, and insists on using A+ tier One lithium iron phosphate cells for its solar batteries.

Which inverters are compatible with CMX Battery batteries?

For 48V inverters, compatible brands include Victron Energy, Goodwe, Studer, Solis, LuxPower, and others. For high-voltage three-phase inverters, compatible brands include Atess, Solinteg, SAJ, Goodwe, and Solis.

What is the warranty for CMX Battery energy storage batteries?

CMX Battery offers dealer customers a 10-year warranty and technical service for its energy storage battery products.

What is Depth of Discharge (DoD)?

DoD describes how much of the battery's capacity has been used. A DoD of 100% means the battery is completely empty, while 0% means it is full.

What is State of Charge (SoC)?

SoC reflects the battery's charge level. A SoC of 100% means the battery is full, and 0% means it is empty.

What is C-rate?

C-rate, or power factor, indicates how quickly a battery can be charged or discharged relative to its capacity. A rating of 1C means the battery can be fully charged or discharged in one hour.

What is the cycle life of a CMX Battery Lithium Solar Battery?

The battery uses Lithium Iron Phosphate chemistry and provides a cycle life of over 6,000 cycles at 90% Depth of Discharge, and over 10 years at one cycle per day.

What is the difference between kW and kWh?

kW (kilowatt) is a unit of power, measuring the rate of energy production or consumption. kWh (kilowatt-hour) is a unit of energy, measuring the total amount of work done or energy used over time.

Where can a home battery be installed?

CMX Battery home batteries are suitable for both indoor and outdoor installation (depending on the model's protection level) and offer floor-standing or wall-mounted options. Common locations include garages, attics, or under eaves.

How long can a 10kWh Powerwall run home appliances during a power outage?

This depends on the load. As a realistic example, a 10kWh battery could run ten 100-watt light bulbs for 12 hours without recharging.

How many home batteries does my house need?

The number varies based on home size, energy consumption history, and personal goals (like which devices to run during an outage). For most systems, 2 or 3 batteries are installed. A detailed discussion of your needs is recommended for an accurate assessment.

Can I go completely off-grid with solar and batteries?

Yes, it is possible, but it requires careful planning and significant investment. A true off-grid system needs a large enough solar array and sufficient battery storage to sustain your lifestyle. Cost and having an alternative energy source for when solar charging isn't possible are key considerations.

Is CMX Battery an online store?

No. CMX Battery focuses on building long-term relationships with business partners like battery distributors, solar equipment dealers, and installation contractors worldwide, not direct sales to end consumers.
