M1200 and M2200 portable power stations

The M1200 (1,030 Wh) and M2200 (2,240 Wh) are plug-and-play LiFePO4 power stations. You switch on the port you need, plug in the device, and recharge from the wall, from solar panels or from a car. This guide follows the English section of each official user manual. Pick your model in the tabs.

Source conflict: model names on the SRP flyer

The SRP flyer in Drive (June 2026) lists the portable stations as "M1800" and "M2400". The specs printed next to those names (1,030 Wh / 1,800 W and 2,240 Wh / 2,400 W) match the M1200 and M2200 in the manuals and datasheets. The flyer names seem to come from the AC output rating, not the model number. Check with the customer which unit they mean, and quote the model on the box (M1200 / M2200).

Rated for 200–240 V / 50 Hz

Both manuals say they cover the version "with an AC output range of 200V-240V/50Hz", and the datasheets list AC input and output as 220–240 V @ 50 Hz. The Philippine grid is 60 Hz, and the documents do not mention 60 Hz operation. Confirm 60 Hz compatibility of the stock you are selling with Silvera Solar Power / MARSTEK.

Car charger / DC outputUp to 12 V / 10 A (shared)

Other parts shown in the manual: resettable overload protection switch, AC output switch, heat-dissipation fan, extra battery port. The manual says "Extra battery need to buy separately".

Source conflict: M1200 AC input and dimensions
  • AC input: the manual says 1,200 W. The datasheet spec table and cover both say 1,000 W max (220–240 V @ 50 Hz).
  • Dimensions: the manual says 462.7 × 195 × 247.8 mm. The datasheet says 400 × 195 × 200 mm. Both documents agree on 1,030 Wh, 14 ± 0.5 kg and 1,800 W AC output. Quote the conservative 1,000 W AC input until MARSTEK confirms which figure is correct.

The LED display switch​

Both models have a LED Display Switch next to the screen:

  1. Short press: turns the display on or off.
  2. Long press: resets the Bluetooth pairing information.

Reading the screen​

The screen lights up when any function is active. You can switch it off with the display button to save power. The manual numbers ten indicators:

#Indicator#Indicator
1Expansion pack (extra battery connected)6AC charge power
2Over-temperature / "overcharge" alarm (see conflict note)7Solar (XT60) charge power
3Bluetooth status8AC output power
4Wi-Fi status9DC output power
5Timing function10Battery percentage

Timing function icon: on means the user has set "no-load shutdown" in the app, so the AC output turns off automatically after the set time. Off means "AC output never to be shut down" is set, so the AC stays on until the battery is depleted.

The IN values show the charging power and the OUT values show the real-time power your devices are drawing. You can estimate the remaining runtime from the battery percentage.

Source conflict: indicator 2

The English manuals for both models label indicator 2 "Overcharge alarm". The German (Übertemperatur-Alarm) and Italian (Allarme di sopratemperatura) sections of the same manuals call it an over-temperature alarm. The English label is probably a translation error. Treat indicator 2 as a temperature warning and check ventilation.

2. Using the outputs​

1

Turn on the port

Press the power switch next to the port you want to use (AC, DC/car, or USB).

2

Check the indicator

When the indicator light next to the port is on, the port is live. Plug in your device.

3

Stay within the rating

AC output limit: M1200 1,800 W (peak 3,600 W), M2200 2,400 W (peak 4,800 W). Above the limit, over-power protection shuts off the AC output. Remove the load, then press the button to reactivate.

4

Turn the AC off when idle

The manual says: "Please press the power button to turn it off when not using the AC power port to save power." You can also set a no-load / light-load shutdown timer in the app.

Example runtimes from the manuals​

These are MARSTEK's own examples, printed in the manuals ("Chargeable device" page). Real runtimes vary.

3. Charging​

Before you use or store the product, the manual says to charge it with the power cord. While charging from the mains, the screen shows the battery level, and 100% means fully charged.

MethodManual charge timeNotes
AC input≈ 1.3 hSupplied AC cable
Solar (XT60)1.5–5 h with an 800 W solar panelMPPT. 12–59 V DC, max 800 W. Panels sold separately
Car charger9–12 hVehicle input up to 120 W

Solar charge times "depend on the weather, temperature, battery status and other factors" (manual).

Other-brand solar panels

Both manuals say you can use solar panels from other brands if they meet these specs: 12–59 V DC, max 800 W (M1200) or 600 W × 2 (M2200). Panel voltage must stay within that 12–59 V range.

Dual (AC + solar) charging and UPS/EPS

The M1200/M2200 manuals and datasheets do not describe simultaneous AC + solar charging, pass-through charging, or a UPS/EPS switchover function. Do not promise these features to customers until MARSTEK confirms them in writing.

Charging temperature: 0–40 °C (both models). Below freezing, the manual recommends keeping the unit in an insulated or temperature-controlled space while it charges.

4. Expansion batteries​

Both manuals show an extra battery port and say the extra battery is "bought separately". The manuals do not give connection steps. The datasheets list these expansion batteries:

P1200-M (connects to M1200)
Capacity1,030 Wh LiFePO4
Lifecycle6,000+ cycles to 80% capacity
Weight11.5 kg
Dimensions400 × 195 × 200 mm
DoD90%
Total with M1200"Easily Expandable to 2060Wh" (datasheet)

The M1200 datasheet shows 1 external battery port.

When an expansion battery is connected, the screen's expansion pack icon (indicator 1) is shown. Check expansion-battery availability and pricing with Silvera Solar Power. Neither battery appears on the current SRP flyer.

5. MARSTEK app (Bluetooth / Wi-Fi)​

The manual says the MARSTEK APP connects to your devices via Bluetooth or Wi-Fi to track energy use and production in real time, show device status, and control the device. In the app you can set the no-load / light-load AC shutdown timer.

1

Download the app

Android: Google Play. iOS: App Store. You can also scan the QR code printed in the manual ("APP Instructions" page). The manual also prints a direct download link: https://eu.hamedata.com/ems/apk/marstek/index.html.

2

Open the app user guide

The manual's second QR code ("Scan the QR code to access the APP user guide") opens the step-by-step pairing guide. The manuals themselves do not list pairing steps.

3

Confirm the connection

The Bluetooth and Wi-Fi status icons (indicators 3 and 4) show the connection state. To pair with a new phone, long-press the LED display switch to reset the Bluetooth pairing information.

6. Storage​

  • If the unit won't be used for a long time, top up the charge every 3 months, keep the battery at 60–80%, and store it in a cool, dry place (manual).
  • Storage temperature: −10 to 45 °C (manual and datasheet).
  • Do not store it in direct sunlight for long periods, such as in a car or cargo bed.

7. Safety​

From the manuals' "Warnings!" section
  • Supervise closely when the unit is used near children. Do not put fingers or hands into the product.
  • Do not exceed the output rating. Overloads can cause fire or injury.
  • Do not use it with a damaged cord, plug or output cable, or if the unit or a battery is damaged or modified.
  • Do not disassemble it. Servicing must be done by a qualified person using identical replacement parts.
  • Keep it away from fire. Temperatures above 130 °C may cause an explosion.
  • Charge only in a well-ventilated area, and never block the fan or vents.
  • Do not use it near strong static or magnetic fields, or flammable or explosive gas or smoke. Do not stand on it.
  • Do not immerse it in water. If it falls into water, put it in a safe, open place away from fire until it is completely dry. Unlike the V500, the M-series has no IP rating in its documents.
  • It is normal for the unit to feel warm while charging a device.

Air travel: the manuals' FAQ says no. The M-series cannot go on an aircraft, because it is well above the 100 Wh lithium-battery limit.

8. Warranty​

The M1200 and M2200 manuals state a 5-year warranty from the purchase date ("Register Now to Get 5 YEARS WARRANTY!"). Proof of purchase may be required. Mechanical impact, unauthorized repair, misuse, and water, humidity or heat damage are excluded. Confirm current local warranty handling with Silvera Solar Power.
