Based on this review alone: buy it if you care about effective anti-islanding protection ensures safety when unplugged — just accept round-trip efficiency is approximately 70%, incurring some energy loss during charge/discharge cycles.
The reviewer concludes that the specific plug-in solar system tested exhibited "no obvious safety risks," citing effective anti-islanding protection and safe handling of reverse power flow through RCBOs. However, a crucial caveat is issued regarding "uncontrolled scaling" with multiple units, which could introduce safety issues, and emphasizes that not all plug-in solar products will perform identically. Economically, the panels offer a payback of under 2 years, while the battery storage through arbitrage has an estimated 7-year payback.
This review investigates the feasibility and safety of plug-in solar systems in the UK, where they are not yet officially sanctioned. The reviewer installs a setup comprising two solar panels and a DJI Power 2000 battery storage system, performing a series of safety tests and an economic analysis. The aim is to determine if this DIY solar approach presents a viable future energy solution.
The DJI Power 2000 is a highly capable portable battery system that effectively stores and arbitrages energy from plug-in solar setups, offering a viable solution for supplementary home power. Its anti-islanding protection was confirmed to work perfectly during testing, cutting power instantly upon unplugging, demonstrating a key safety feature. While the round-trip efficiency is around 70%, the manufacturer transparently displays this data, allowing users to understand the effective cost of stored energy. If you are looking to integrate a flexible, expandable battery storage system with a plug-in solar array for energy savings and backup power, this unit is worth considering. If you require higher round-trip efficiency or a permanent, hard-wired installation, you may need to explore other options.

The reviewer estimates that two panels with a combined peak output of 800W would generate approximately 750 kilowatt hours of energy over a year, translating to roughly £190 in savings at current electricity prices.
hands_on_demopositivet=1:09–1:19
On the sunniest day of the year, the system demonstrated over 500 watts of generation from the panels, with about 400 watts flowing into the DJI Power 2000 battery and the remainder powering household loads.
hands_on_demopositivet=1:28–1:44
The reviewer demonstrated that disconnecting the 13-amp plug from the mains immediately removed voltage from the plug pins, confirming the microinverter's anti-islanding protection was functional and safe.
hands_on_demopositivet=2:05–2:22
During reverse power flow, the reviewer successfully pushed the test button on an RCBO, which tripped off safely without any damage, countering concerns that such an action could destroy the device.
expert_opinionpositivet=2:39–2:56
The reviewer explained that microinverters employ an isolated construction, effectively separating the DC and AC sides, which minimizes the risk of DC leakage currents that could potentially affect older Type AC RCDs.

The reviewer successfully expanded the DJI Power 2000's total storage capacity from 2 kWh to 6 kWh by easily adding two expansion battery packs.
reviewer_claimpositivet=4:33–4:49
The reviewer notes that despite a grid-tied export cap of 800W, the system can simultaneously draw 800W from the solar inverter and 800W from the battery, significantly increasing available energy and flexibility.

After monitoring for a few months, the reviewer determined that the DJI Power 2000's round-trip efficiency for energy storage and discharge was approximately 70%.
measurement_testpositivet=5:35–5:44
By charging the battery on an off-peak tariff of 7p/kWh and effectively paying 10p/kWh for usable energy, the reviewer calculated daily savings of approximately £1 from energy arbitrage alone.
measurement_testpositivet=5:44–5:50
Based on the calculated daily arbitrage savings, the reviewer estimates a payback period of approximately 7 years for the battery storage technology.
measurement_testpositivet=5:58–6:05
During the filming of the video, the integrated system stored an additional 1.3 kilowatt hours of energy that otherwise would have been exported to the grid.

The reviewer highlights the DJI Power 2000's built-in UPS function, which proved effective in keeping essential equipment powered during a planned power outage on the local network.
The reviewer performed tests confirming the microinverter's anti-islanding protection safely cut power to the plug pins when disconnected. The system also safely handled reverse power flow through an RCBO, tripping without damage. Furthermore, microinverters' isolated construction helps mitigate concerns about DC leakage currents. The reviewer observed no obvious safety risks with this particular setup.
A typical 800W plug-in solar setup is estimated to generate 750 kWh/year, leading to roughly £190 in annual savings and a payback period of under two years, assuming most energy is self-consumed. Pairing this with a battery system like the DJI Power 2000 for energy arbitrage can yield additional savings of approximately £1 per day, resulting in an estimated 7-year payback for the battery storage component.
The reviewer demonstrated the easy expansion of the DJI Power 2000's storage capacity by adding two expansion packs, boosting the total to 6 kilowatt-hours. The main unit instantly recognizes the additional capacity upon power-up, and the process involves simply stacking and connecting the supplied leads.
After several months of operation, the reviewer measured the DJI Power 2000's round-trip efficiency for energy storage and discharge to be around 70%. This efficiency is considered acceptable, attributed to inherent losses from AC-DC and DC-AC conversions, internal cell resistance, standby consumption, and potentially an isolated topology design for enhanced safety.
The DJI Power 2000 provides a built-in UPS function, which the reviewer confirmed as effective. It successfully kept essential equipment plugged into its front outlets powered during a loss of mains supply, specifically noting its utility during planned local network maintenance.
100/100 source quality
The eFIXX channel conducts an in-depth test of a plug-in solar setup in the UK, evaluating both its safety and economic potential in a regulatory grey area. The video features demonstrations of the system's anti-islanding protection and its safe operation when reverse power flows through an RCBO, alongside a discussion on DC leakage concerns. The system is integrated with a DJI Power 2000 battery, which is shown to have 70% round-trip efficiency for energy arbitrage and an approximate 7-year payback period. While the reviewer identifies no clear safety risks with their specific configuration, they express concerns about the broader implications of uncontrolled widespread deployment.
