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 R4000 is used to power a 700Wh heater, the runtime would be 3600Wh x 86% x 80% ÷ 700 ≈ 3.5 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 R4000 is used to power a 100Wh MacBook and a 100W drone, the runtime would be 3600Wh x 86% ÷ 200W ≈ 15 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 R4000 has a 4000W AC output (6000W peak), allowing you to power devices with a rated power of up to 4000W and a peak power of up to 6000W.

The R4000 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, the R4000 is designed to integrate seamlessly with solar photovoltaic systems like those found on balconies and rooftops. The R4000 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 R4000's DC input. This allows the solar panels to charge the R4000 battery bank directly.

B.E here again as the frist 2 reviews are mine had the r4000 now about 4 months
There is so mush to like about this product will list a few I like

2000w of solar an essy to connect
Feels well built looks great
4000w of power it's a lot
Connect to your phone Internet
Easy to move
The battery is very good get about 3100 wait hours from it after the inverter cost so is true to battery save

Problem with r4000

Can not connect Bluetooth to my phone
It estimates the time for how long the battery got left is crazy can be using 1000w an will say 6 hours left if battery is full but this is not true only got about 3 hours way lie 1000w times 6 hours would be at lest 6 kw battery with out the inverter cost
The biggest problem can not link an r4000 to gather or b3000 right now I think just mail support to see if this has changed as when I payed for 2 r4000 on the site said I would be able to link up to 6 together picters on there site an now see thay have put on this site can link to a b3000 would be great if thay have fixed this if thay do mail me back I can connect a r4000 or a b3000 will delete these reviews an write you a 5 star as the product will be sweet I'm trying to love but 3.6 kwh is just not big a nuff tell allpower fix this I would tell people to go for r3500 pluses b3000 say on sit can get over 100kwh with lots of batteys
