V500: Waterproof 500 W / 2 kWh Solar Generator with 500 W PV Input · Silvera Solar Power (AI-generated scene, official product design)

What it is: the V500 is a compact, IP65 waterproof, fanless solar generator with a 2,009 Wh LiFePO4 battery and a single 500 W pure-sine-wave AC outlet (230 V / 50 Hz per the datasheet and manual). It charges from a solar panel (MC4, 500 W max), from the grid (500 W), or from both together (750 W total), and can pass grid power straight through to the load (bypass).

Who it's for: households that want a plug-and-play brownout backup for small essential loads (router, lights, fans, phone charging, a small TV) without an electrician, and users who want something weatherproof and silent for outdoor use.

Best for​

  • Essential-load brownout backup up to 500 W continuous: Wi-Fi router, LED lights, electric fan, phone and laptop charging.
  • Solar-only charging where there is no grid, or grid + solar charging for the fastest refill (750 W combined).
  • Outdoor or damp locations: IP65, natural cooling, rated to 4,000 m altitude.
  • Customers who want a silent unit (fanless).

Not for: running loads above 500 W rated (aircon, rice cooker, flat iron, water pump). The V500 will stop and enter protection. For those, see the M1200, M2200 or V6000.

Key features​

From the V500 datasheet and manual:

  • 500 W pure sine wave output, 1,000 W peak; one universal socket.
  • Flexible charging (manual §4.2):
    • AC IN only: 500 W.
    • PV only: depends on the solar panel (500 W max).
    • Dual (AC + PV): 750 W total. If PV is strong, PV is capped at 500 W and AC IN supplies 250 W. If PV is under 500 W, AC IN rises to keep the total at 750 W.
  • Simultaneous charging and discharging (manual §4.4):
    • AC IN + load: full bypass, so grid power supplies the load.
    • PV + load: PV supplies the load and the battery covers any shortfall.
    • AC IN + PV + load: grid supplies the load while PV charges the battery.
  • Wide input voltage range of 184–276 V for unstable grids.
  • 10,000+ cycles to 80% DOD (datasheet; see conflict note below).
  • MARSTEK app over Bluetooth or Wi-Fi (Android 6.0+, iOS 12.0+).
  • Battery protection: overcharge, over-discharge, overcurrent, over-temperature, short-circuit and overvoltage protection (manual §1.3).
  • Front LED panel: AC IN, AC OUT, 4-bar battery level, WARN (red on fault), PV, WIFI/BT.

Installation & safety​

The V500 is plug-and-play (no fixed wiring), but the manual still sets firm rules:

Do not overload

Do not power loads above 500 W rated. Overloading stops the V500 and puts it into protection. Exceeding the rated output may cause fire or injury.

  • Use: connect only officially certified electrical or electronic devices; use only MARSTEK-recommended or supplied accessories; unplug by the plug, not the cord.
  • Placement: dry, well-ventilated area away from liquids; keep vents and cooling parts unobstructed; never near open flames, heaters or flammable or explosive materials. Do not expose to temperatures above 130 °C.
  • Do not open: high voltage inside. Disassembly or repair only by qualified personnel. Wait 5 minutes after power-off before maintenance.
  • Handling: carry by the handles, upright. Do not drop from above 0.5 m; support it on stairs.
  • Power off: disconnect AC IN, PV+ and PV- first, then press and hold ON/OFF until the green ring turns off.
  • Storage: -20 to 60 °C, ≤95% RH, indoors, upright, at 50–60% SOC; top up every 1–2 months. Before reuse after long storage, charge to above 80% and check for heat or noise.
  • Routine check: inspect at least once every six months.
  • Children: keep out of reach; close adult supervision required.
  • Warranty: the manual says the period is "subject to the warranty card enclosed with the product". Confirm the local term with Silvera Solar Power.
