Growatt APX 25 kWh – from this capacity the number of phases changes the power
Growatt APX 25 kWh this is the configuration APX 25.0M-S3: master module APX 5.0M-B3 and four battery modules APX 5.0P-B3, column 1485 mm high and 233,2 kg in weight. This capacity is the first in which the data sheet provides different power values for single-phase and three-phase installations.
Do 20 kWh both columns of the manufacturer's table contained the same numbers. At 25 kWh The single-phase system stays at 10 kW maximum power and 14 kW peak power, while the three-phase system switches to 12,5 kW and 17,5 kW for 10 seconds. If the design is about power, not just energy reserves, then the decision on the number of phases is no longer solely an installation decision.
Unified Master Module - Why 2.0 Doesn't Tell You to Choose a Phased Version
Cover card APX HV Battery 2.0 replaces unified master module compatible with both single and three phase systems. In practice, this means that the same master module APX 5.0M-B3 supports both systems, and the difference comes down to operating parameters, not a different catalog number. A storage unit purchased for a single-phase installation does not become unusable after the connection is expanded to three phases.
Set composition 25 kWh
Configuration 25 kWh is one column composed of five elements: the master module APX 5.0M-B3 and four battery modules APX 5.0P-B3The master module sits at the top of the column and contains the battery management and its own 5 kWh capacity.
The base is included. The master module comes pre-assembled with a stand, and the packaging includes the stand and wall mount—no need to purchase a stand or separate battery management box. The stand is from an older generation. APX doesn't fit: older modules have a projection of 690 × 185 mm, 2.0 modules - 590 × 255 mm.
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.
Who is this capacity for?
- Three-phase power-oriented installations — 12,5 kW maximum and 17,5 kW for 10 seconds are values that a single-phase system with this capacity will not reach.
- Objects with engine start-up — 17,5 kW peak for 10 seconds supports the start-up of inductive loads without reserving power in the inverter.
- Farms with two large loads transferred overnight — heating plus charging the car, while maintaining the morning reserve.
- Small companies with single-shift work - 25. kWh covers the daily consumption of a workshop or office without entering a two-cluster configuration.
25 kWh in single- and three-phase systems
Same column 25 kWh behaves differently depending on the installation. In a single phase, it provides 10 kW of maximum power and 14 kW of peak power – the same as a 20 configuration kWhIn a single-phase system, the buyer therefore pays for the fifth module solely in energy, not power. In a three-phase system, the same column produces 12,5 kW and 17,5 kW for 10 seconds.

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 listed on the data sheet as Cobalt Free Lithium Iron Phosphate. Peak power is 14 kW/10 s in single-phase and 17,5 kW/10 s in three-phase. 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
Column 25 kWh It is 1485 mm high and weighs 233,2 kg – with this value, floor mounting is in practice the only reasonable solution, although the card formally also allows for wall mounting and then requires confirmation of the wall's load-bearing capacity. The dimensions of 590 × 1485 × 255 mm include the system's base.
- 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.
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 fit before purchase. If the inverter isn't already in your project, start with the single-phase hybrid inverters category.

Most frequently asked questions
How many modules does the warehouse consist of? Growatt APX 25 kWh?
Of the five: one master module APX 5.0M-B3 and four battery modules APX 5.0P-B3. The configuration catalog number is APX 25.0M-S3The set also includes a three-phase smart meter. Growatt, in our catalogue index 00005 - no need to purchase it separately.
Is the base included?
Yes. The master module is shipped pre-assembled with the base, and the packing list includes the base and wall mount. When adding battery modules, the base is removed and moved to the bottom of the speaker. The base is from an older generation. APX does not fit - older modules have a projection of 690 × 185 mm, 2.0 modules have 590 × 255 mm.
Why 25 power kWh is different for one phase and different for three phases?
The datasheet states: 10 kW maximum and 14 kW peak in a single-phase system, and 12,5 kW and 17,5 kW for 10 seconds in a three-phase system. The datasheet states that the power of the entire system is further limited by the inverter and battery capacity.
Is it 25? kWh is this another column?
Yes. One column consists of one master module and a maximum of five battery modules, i.e. up to 30 kWhThe second column only appears above this value.
What is the operating voltage of this warehouse?
The nominal voltage is 400 V in a single-phase system with an operating range of 350–550 V and 750 V in a three-phase system with an operating range of 660–980 V.
Does the warehouse require mechanical ventilation?
No. The data sheet states natural cooling, without fans, and an IP66 protection rating with an operating range of -20 to 55 °C and humidity of 5–95%.
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.
