Frequently Asked Questions

he runtime can be calculated as follows:
Runtime = Battery Capacity x Depth of Discharge x Inverter Efficiency ÷ Rated Power of the device.
For example, if the R3500 is used to power a 400Wh e-Bike, the runtime would be 3168Wh x 86% x 80% ÷ 400 ≈ 5.5 hours.

Or you can calculate here how long power stations with different outputs can supply your system.

DC Output Runtime = Battery Capacity x Depth of Discharge ÷ Rated Power of the device.
For example, if the R3500 is used to power a 100Wh MacBook, the runtime would be 2016Wh x 86% ÷ 100W ≈ 21 times.

The above date is for reference ONLY. Please note that the formula is NOT suitable for inductive loads with compressors, like refrigerators, air conditioners, etc.

The R3500 has a 3500W AC output (6000W peak), allowing you to power devices with a rated power of up to 3500W and a peak power of up to 6000W.

The R3500 has an XT60 port for a maximum of 2000W solar input. You can use a 12~150V 40A solar panel to charge.

Recommended panels:


SP039 - 600W Foldable,

SP037 - 400W Foldable,

SF400 - 400W Flexible,

SP033 - 200W Foldable,

SP035 - 200W with monocrystalline cells

Yes, you can charge the R3500 with a 12V/24V car cigarette lighter. You will need a Car to XT60 cable.

Yes, the R3500 is designed to integrate seamlessly with solar photovoltaic systems like those found on balconies and rooftops. The R3500 stores excess solar energy generated during the day in its internal battery bank. This stored solar electricity can then be used to power your home's essential appliances and electronics when grid power is unavailable.

To connect it to your balcony PV system, simply wire the solar charge controller to the R3500's DC input. This allows the solar panels to charge the R3500 battery bank directly.
