SATURN: Select memory and inverter together
SATURN as a balcony system.
The B2500-D stores solar power on the DC side. A separate micro inverter converts it for the house network. Both devices remain individually selectable.

SATURN B2500-D · Memory
2,24 kWh per device. In the manufacturer's circuit up to four memory with 8,96 kWh.

For this memory combination: the 800-W version with two MPP trackers.
The combination shown depends on the Manufacturer connection for B2500-D. Device design, cables and power limitation we vote for your system.
Model or capacity already known?
Look for a MARSTEK model, system configuration or nominal energy in kWh.
Which MARSTEK solution fits your system?
AC memory: The VENUS-E versions, VENUS G and VENUS X are guided after their documented AC coupling. PV inputs are not available for every generation. VENUS D and the own AC version are shown separately.
DC and hybrid solutions: Systems with documented PV-DC inputs can be found under DC storage systems. With MARS I PLUS, single and three-phase devices are different versions. An identical name on the battery module does not confirm interchangeability.
Integrated or separately: With integrated balcony systems, storage and inverters sit in the device. SATURN B2500-D uses a separate SATURN-M micro inverter. The documented 2-MPPT-/800-W combination is under DC; the memory is also available under batteries & extensions.
Capacity and power: Nominal energy is in kWh, inverter power in kW or kVA respectively. Usable energy is not calculated from a DoD percentage. The exact connection and power level belongs to the selection.

Which series are in this selection?
The current selection includes VENUS E Pro, E Max, E 4.0, E Mini and E 3.0, VENUS D and D AC version, JUPITER C PLUS, SATURN-C B2500, V6000, VENUS G, VENUS X and MARS I PLUS single and three-phase, MARS II and MARS I SE. VENUS E 1.0, VENUS E 2.0, VENUS C and the JUPITER C/E document generation are separated in the memory archive. Offgrid and mobile complement V500, MERCURY M1200, MERCURY M2200 and the EU version M5000-N with P5000-N.
Why do we distinguish VENUS-E generations?
The designations stand for different devices: VENUS E 3.0 calls 5,12 kWh, while E 4.0 calls 5.024 Wh. VENUS E Max calls 10,048 kWh. In the E Pro, the documented extension starts with 2,08 kWh; E Mini calls exactly 2.009,6 Wh, i.e. approximately 2,01 kWh. These values are not estimated from the model names.
How are modular systems displayed?
The variant lists connect the documented device type with the permissible number of battery modules. With the E Pro base battery and additional modules count together; with the JUPITER C PLUS up to three additional batteries are documented. For MARS I PLUS and MARS II the inverter versions are also individually named.
What information is still open?
The VENUS-G brochure mentions one to six battery modules, but no explicit rated energy. Therefore, there is no capacity derived from ‘5.0KBAT'. With VENUS E 3.0, the formulations for capacity and useful energy differ within the prospectus. We clarify such points before the concrete interpretation.
Which documents are used?
Unchanged original data sheets from the manufacturer download area are linked. EU versions are preferred; international English documents are identified as such. The verification date 09.11.2026 is the call date and no invented revision date. An international listing confirms neither inventory nor any connection execution for your project.
What's in the memory archive?
The memory archive contains VENUS E 1.0, VENUS E 2.0, VENUS C with 2,56 kWh and the previous JUPITER C/E file. Previous generation and document names are explained at the download. At VENUS C we carry out the documented execution without an unconfirmed subdivision into 1.0/2.0. The archive assignment describes our document stock and no flat-rate manufacturer termination.
Which details help with the request?
Name the exact model and generation name, desired capacity, existing PV system, inverter and connection options. For extensions help typeplate, existing modules and system status. The product action takes over the selected configuration into the central contact form.
