No. The Guardian 6000 V2 is only compatible with G5 extra battery (each with a 4,608Wh capacity).

The Guardian 6000 V2 is compatible with 240V AC charging. To utilize this function, please purchase a 240V AC charging cable and connect it directly to a 240V AC outlet.

The Guardian 6000 V2 's 240V/50A outlet works with EV chargers. However, please note that the Guardian 6000 V2 typically uses a floating ground. You will need to purchase a plug or portable EV charger that can adapt a floating ground to a ground-neutral bond. OUPES does not currently sell such products, so we recommend purchasing an item similar to the one in the linked product from other stores.

No. The Guardian 6000 V2 does not support parallel connection. A single unit provides 6,000W of rated output and can briefly supply up to 7,200W in Boost Mode. This output capacity is sufficient to power virtually all common household appliances.

Yes, it is safe to leave the Guardian 6000 V2 connected to your solar panels overnight. We've optimized the Guardian 6000 V2's internal circuit design to enable 24/7 automatic charging management, so the MPPT controller will stop charging when there's no sunlight and automatically resume when the sun returns. This will not cause any damage to the unit or your panels.

No.

• When charging with 120V input, it supports 120V AC output and DC output.
• When charging with 240V input, the AC output is disabled, but DC output remains active.
• During solar (PV) charging, both AC and DC outputs can operate simultaneously.

Yes, you can. Please make sure the panels are compatible — the open-circuit voltage should be ≤ 165V, the current ≤ 25A, and the total power should match the MPPT specifications.

Yes. The Guardian 6000 supports pass-through charging. However, in bypass mode, AC charging input plus all outputs should not exceed 2,400W.

The Guardian 6000 V2 is set to stop charging at 90% capacity by default to help protect the battery and keep it performing well over time. If you’d like it to charge to 100%, you can easily adjust the charge limit in the Cleanergy app.

Li-ion batteries include various types, such as LiMn2O4, LiCoO2, and LiFePO4. LiCoO2 and ternary lithium batteries have shorter lifespans compared to LiFePO4. Customs requires products to be labeled according to their classification, and both types are considered lithium-ion batteries. You can verify the use of LiFePO4 batteries by checking the packaging and specification label.

The charging time depends on the battery capacity and the charging speed of your power station. We use the following formula to estimate the charging time:

Estimated Charging Time = (Battery Capacity / Charging Speed) * 0.85

Please note that this is only an estimate.

For example, to charge a Mega 5 with AC power (maximum charging speed of 1800W and capacity of 5040Wh):

Estimated Charging Time = (5040 / 1800) * 0.85 ≈ 2.4 hours.

No, none of the Mega series products use this setting.

Yes, you can use a "briefcase" style solar panel with its own charge controller, provided that the current output from the controller is lower than 15A.

Sideways placement is not recommended for the Mega series.

Mega series products do not support this usage.

The B2 backup battery has MPPT for solar charging, while the B5 backup batteries do not include MPPT (Maximum Power Point Tracking).

The length of the solar panel is 16.4 ft.

If you want to extend them, you can choose MC4 extension cables.

One pair can extend 20 feet, 2 pairs can extend 40 feet, and so on.

Here is a link to the MC4 extension cable for your reference.

Yes, this function is supported for Mega 2, Mega 3, and B2 batteries. However, it is not available for B5 batteries because they do not include MPPT.

No, the display will automatically turn off to conserve power.

You need to shut down the device before adding or merging batteries.

Nothing will happen; the system will automatically limit the charging current.

Yes, you can, but the output current of the DC-DC charger must be lower than 15A.

Yes, you can connect solar panels to both the battery input and the main unit input simultaneously.

Yes, you can use the battery pack to charge the main unit. When connected, power will flow from the battery pack (the higher side) to the main unit (the lower side). As the battery pack discharges and the main unit charges, the power levels will eventually balance, at which point the battery pack will stop charging the main unit.

The Mega series has a high charging input power, which may occasionally cause the circuit to trip, resulting in the product not responding. This does not indicate a defect in the product. The usual solution is to check the main circuit breaker after a trip and then switch it back from "off" to "on."

Due to the weight of the products, we recommend against stacking them. If you choose to stack them, do not stack more than five units. Additionally, please note that the Mega 2 and Mega 3 can each connect to up to six spare batteries, while the Mega 5 can connect to up to eight spare batteries.

The B2 battery does not have an external charger, it can be charged directly from the Mega 3 or solar panel

The Mega does not need to be fully charged to activate the EPS function. When the Mega is connected to a wall socket for charging and the freezer is connected to the Mega with the AC output turned on, the system will automatically switch to the Mega's power supply if the wall socket loses power.

Currently, only Mega 5 can do.

For the Mega series, we recommend charging the unit until the fan icon on the screen stops spinning. This ensures the battery is fully charged before first use.

The device showing reverse polarity when plugged into AC power may indicate issues with the outlet, plug wiring, or internal circuitry. This can disrupt pass-through charging and UPS functionality, leading to malfunctions.

Address this issue immediately by checking the outlet or using a different one. If it persists, consult a qualified electrician or the manufacturer.

Do not use the device with reverse polarity, as it poses safety hazards and could cause damage. Verify your wiring method.

No, the Exodus 600 cannot be charged via a car charger.

Most solar panels on the market are compatible, but you should check that the specifications and plug match (within 150V, and the connection port is Anderson). Feel free to contact us via email before making connections.

We recommend connecting OUPES solar panels with OUPES solar generators, as they include optimized solutions. While third-party solar panels may work, different companies' solutions can conflict, potentially reducing charging efficiency.

The input power will not exceed 15A, which is safe

Our solar panels have waterproof treatment, but we do not recommend using them in the rain. Portable solar panels cannot be fully waterproofed like hard solar panels, and long-term exposure to rain may reduce cell efficiency.

The length of the solar charging cable is 16 feet, and we also offer extensions on our website. Please note that charging efficiency may decrease with longer cables, potentially requiring more time to fully charge.

Here are some ways to potentially speed up the charging of your solar panels

1.90 degree postion facing the sunlight
2.all the solar panel face to the sunlight towards the same direction
3.we recommend our customers to charge the OUPES generator with the OUPES solar panels.
It will achieve the maximum power input.
4.no obstruction, even a leaf may affect the charging efficiency
5.maybe the solar panel is aging so the working efficiency is low

Not required, there is a built-in fuse box inside the product

Solar generators are generally not affected by wind and snow, but heavy snow can cover the panels and reduce effectiveness. Our solar panels have over 20% efficiency and can operate in winter, though power output may be lower due to less sunlight. They function within a temperature range of 14°F to 158°F.

The plastic clips you received are called foot guards. They are designed to elevate the solar panel slightly off the ground, preventing direct contact and potential abrasion.

The PV system begins charging at dawn; however, the voltage during this time can be unstable. This instability may cause issues with the initialization of the microcontroller unit (MCU) that manages the Maximum Power Point Tracking (MPPT). It can also affect the inverter switch, which may continue to output power even after being turned off.

For optimal performance, we do not recommend plugging the solar panel in overnight. If you avoid these incorrect practices and still experience issues with PV charging, please provide us with the specific parameters of your PV panel and the connection method (including the number of strings and how many are in parallel). This information will help us diagnose the problem more effectively.
