Sungrow MBH battery module (5.22 kWh)

Official manufacturer IEC / MEA / SEA verified Sept. 22, 2026

category	batteries
generation	MBH
hardware_revision	—
legacy_name	—
manufacturer	Sungrow
market_version	Datasheet V3 MEA APAC (2026)
model	MBH battery module (5.22 kWh)
product_family	MBH (MBH20~75)
product_status	active
product_status_evidence	Component of the MBH range, itself active on datasheet V3 (2026)
region	IEC / MEA / SEA
release_year	—
sku	—
subcategory	battery module (component of an MBH cabinet)
variant_note	THIS IS THE MODULE, NOT A CABINET. Unlike the SBR and SBH modules, Sungrow prints this module's own voltage and Ah, so they are recorded as facts rather than derivations.

architecture	Series element of a 4-15 module MBH stack
cell_chemistry	LiFePO4
chemistry	LFP (LiFePO4)
current_note	The 100 A figure is a SYSTEM/product-page figure and was not carried down to the module.
cycle_life	Up to 6,000
cycle_life_note	Range-level claim.
depth_of_discharge_pct	90.0
expansion_rules	'Scalable 4-15 module system, max 78 kWh'

cooling	Natural convection (as part of the cabinet)
depth_mm	—
dimensions_note	Module dimensions are not printed; only the cabinet's 534 x 1458/2030 x 560 mm.
height_mm	—
ip_rating	—
mounting	Stacked in the MBH cabinet
weight_kg	—
weight_note	NOT printed and deliberately NOT derived. The cabinet weights imply ~41 kg/module between MBH20 and MBH40 but ~47 kg/module between MBH40 and MBH75, because the range uses two different cabinet heights - so no single module mass can be honestly inferred.
width_mm	—

indoor_outdoor	Indoor (as part of the cabinet)
supported_installation_topology	Series element of one MBH cabinet

charge_temperature_c	0 to 55
discharge_temperature_c	-20 to 55
humidity	5 % to 85 % no condensing
max_altitude_m	2000
noise	—
operating_temperature_max_c	60.0
operating_temperature_min_c	-25.0
storage_temperature_c	—
temperature_note	Inherited from the MBH cabinet datasheet; charge and discharge windows differ.

can	—
communication	CAN, RS485
communication_protocol	—
ethernet	—
ports	Module interconnect; CAN/RS485 to the inverter is made at the cabinet.
rs485	—

note	Protections documented at cabinet level ('21 protection functions', DC breaker, reverse connection protection).

listed	['IEC 62619', 'EN 61000-6-1', 'EN 61000-6-2', 'EN 61000-6-3', 'EN 61000-6-4', 'IEC 62477-1', 'UN 38.3']
