Growatt APX 50 kWh – two symmetrical clusters of 25 kWh
Growatt APX 50 kWh is a two-cluster configuration of the family Growatt APX HV Battery 2.0 consisting of two master modules APX 5.0M-B3 and eight battery modules APX 5.0P-B3. Eight modules are divided evenly, four per column, so both columns match the catalog configuration APX 25.0M-S3.
Set composition 50 kWh
Configuration 50 kWh are two clusters working in parallel, ten elements in total: two master modules APX 5.0M-B3 i eight battery modules APX 5.0P-B3Each cluster has its own master module with battery management and its own capacity of 5 kWh in this module.
- Cluster 1 - 25 kWh (APX 25.0M-S3): 1 × APX 5.0M-B3 + 4 × APX 5.0P-B3.
- Cluster 2 - 25 kWh (APX 25.0M-S3): 1 × APX 5.0M-B3 + 4 × APX 5.0P-B3.
We've chosen the division so that each column individually matches the configuration on the catalog card. The card doesn't dictate this, and the columns don't have to be of equal capacity—we confirm the configuration when ordering.
The base is included. The master module comes pre-assembled with the base, and the packing list includes the base and wall mount—no need to purchase a stand or a separate battery management box.
A three-phase smart meter is included in the set. This is a three-phase smart meter Growatt for energy measurement, index 00005 in our catalogue. It does not need to be purchased separately. See the meter card
Single-phase installation? This kit will replace your meter at no extra charge. It has a three-phase meter, and the series instruction manual (chapter 1.1) mentions cooperation APX 2.0 also with single-phase inverters MIN-XH i MIN-XH2If this kit is for a single-phase installation, we will replace the meter with a single-phase one at no extra charge—just specify this in the "Order Notes" field when placing your order. The replacement applies to this kit: the master module and battery module, purchased separately, do not include the meter.
The complete set of cables runs in the master module — the cascade cabling cannot be purchased separately; this is commercial information PVGroup.pl, not a record from a catalog card. A separate item remains connecting element (adapting piece), i.e., the mechanical connection of two columns: the master module accessories bag contains only M6 expansion bolts and M4 screws. This item is not in the catalog today PVGroup.pl — please contact us before ordering.
How many clusters can be connected? The instructions provide for a cascade of two or three systems APX M-S3, and the limit is set by the inverter: series MID-HU supports up to three clusters, series MID-XH – up to two. For the MOD series, the manual doesn't specify this, and we haven't verified it. This configuration runs on two clusters, so it falls within both documented limits.
Who is this capacity for?
- Manufacturing plants - 50. kWh allows a significant part of the consumption to be transferred outside peak hours without interfering with the technological process.
- Medium-sized commercial facilities — refrigeration and ventilation operating 24 hours a day, powered by daily production.
- Installations with critical process support — two independent clusters, each with its own master module and its own battery management.
Symmetric division and cluster parameters
The eight battery modules are divided into two by four, which gives two columns APX 25.0M-S3Each card has a maximum power of 10 kW in single-phase and 12,5 kW in three-phase, with peaks of 14 and 17,5 kW for 10 seconds, respectively.

The values are from the catalog card Growatt APX 5.0-30.0M-S3 (revision 2026-07) and from the series user manual; the cells are recorded on the data sheet as Cobalt Free Lithium Iron Phosphate. The data sheet does not provide maximum or peak power for a dual-cluster configuration, therefore these rows are not included in the table. The data sheet does not include depth of discharge, round-trip efficiency, or number of cycles.
Certificates and standards
Catalog card lists for the system APX 5.0-30.0M-S3 following standards and certificates: IEC62619(Cell&Pack) / IEC60730 / IEC62477-1 / IEC62040-1 / CE(EN61000) / UN38.3 / IEC60529 / REACH / CEC. We will send the certificate in the form of a document on request.
Installation and working conditions
Both columns measure 590 × 1485 × 255 mm and weigh 233,2 kg each. Double-cluster operation is only permitted in floor mounting, so the technical room must accommodate two columns nearly 1.5 meters high, along with a service area, which the data sheet does not specify.
- Degree of protection IP66 and natural cooling, without fans.
- Operating temperature range from -20 to 55 °C — the card lists the heating foil as part of the system equipment.
- Relative humidity 5–95% and work up to 4000 m above sea level.
- Distance between columns 150 mm, and from the wall 25–40 mm - dimensions from the instruction manual for a two-column system.
Compatible inverters
The user manual indicates cooperation with single-phase inverters of the MIN-XH and MIN-XH2 series, and with three-phase inverters - with the MOD and MIDThese are the only families listed in the manufacturer's document and we only declare them.
The inverter is the second system limitation, next to battery capacity. The data sheet stipulates that the system's power is limited by the inverter's maximum charge and discharge power. Submit your inverter model and we'll confirm the kit before purchase. If the inverter isn't already in your project, start with the three-phase hybrid inverters category.
B2B warranty and support
The catalog card gives the series APX 2.0 ten-year warranty. Equipment purchased in PVGroup.pl is covered by a European service warranty, technical documentation for downloadInstallers and integrators can log in and see net prices with a wholesale discount. Lithium cells are subject to hazardous goods transport regulations.

Most frequently asked questions
What does a warehouse consist of? Growatt APX 50 kWh?
Of the two master modules APX 5.0M-B3 and eight battery modules APX 5.0P-B3, spread over two columns of 25 kWhThe set also includes a three-phase smart meter. Growatt, in our catalogue index 00005 - no need to purchase it separately.
Do I need to purchase additional equipment for two-cluster operation?
No cables - the complete wiring is in the master module (commercial information PVGroup.pl). A separate item is the connecting element (adapting piece), which mechanically connects the two columns; the master module accessories bag only includes M6 expansion bolts and M4 screws. This item is not currently in the catalog. PVGroup.pl — please contact us before ordering.
Is it 50? kWh Are there two more clusters or three already?
Two, 25 each kWh each - i.e. it falls within both documented inverter limits, including the lower, two-cluster one.
Is warehouse 50 kWh requires mechanical cooling?
No. The datasheet specifies natural cooling, without fans, for the entire series. APX 2.0, with an operating range of −20 to 55 °C and humidity of 5–95%.
How much does the entire installation weigh?
The sum of the masses of two clusters of 25 kWh is 466,4 kg. This is our calculation from the catalog values - the card does not provide the weight for a two-cluster configuration.
Up to what height above sea level can this warehouse be installed?
The catalog card specifies an operating altitude of up to 4000 m above sea level for the entire series. APX 2.0.
I have a single-phase installation - does this kit make sense?
Yes. The series user manual (chapter 1.1) mentions cooperation APX 5.0-30.0M-S3 with single-phase inverters MIN-XH i MIN-XH2This kit includes a three-phase meter. If your installation is single-phase, we'll replace it with a single-phase meter at no extra charge. Simply specify this in the "Order Notes" field when placing your order. This replacement is for the kit; the master module and battery module, which are purchased separately, do not include the meter.
