Fox is a global leader in the development of inverter and energy storage solutions.  It is part of the Tsingshan Group, a Fortune Global 500 company and the largest producer of stainless steel in the world.

Fox has a large, highly advanced R&D centre in Wuxi, China, where its portfolio of solar inverter and energy storage products was developed.  These include the All-In-One (“AIO”) products, which are fully integrated with 10kWh of high voltage batteries, a 6kW inverter, charge controllers and 2 MPPT’s.  The floor mounted AIO products are a competitively priced plug-and-play solution.

High efficiency – round trip efficiency of up to 97%;

Easy installation – plug and play installation with built-in fuse protections;

EPS function – (for E models only) for off-grid and emergency power;

Easily upgradable/expandable – up to 4 batteries can be installed in series (Ultra range);

Remote monitoring – monitor system remotely using a web portal or smartphone app; and

Safety & security – enhanced safety features using advanced hardware & software protection.

The other products include:

  • Single phase inverters – S Series (1 MPPT) from 0.7-3.3kW AC Power and F Series (2 MPPT) from 3.0-6.0kW AC Power
  • Three phase inverters – T Series (2 MPPT) from 3-25kW AC Power
  • AC Charger
  • AIO AC-coupled and Hybrid units
  • High voltage batteries


Victron Energy, based in the Netherlands, have been manufacturing power conversion equipment since 1975 and become well known around the world for producing reliable off-grid battery inverter/chargers and a wide range of quality, affordable solar controllers.  Victron’s higher power combined inverter & chargers, the MultiPlus and Quattro range, along with an array of smart energy management devices are well priced for the residential market.   These products features include true sine wave inverter, adaptive charging, hybrid PowerAssist technology plus multiple system integration features such as three or split phase operation and parallel operation.

Whilst the Multiplus II has one AC input, the Quattro can be connected to two independent AC sources and will automatically connect to the active power source. The main output has no-break functionality. In the event of a AC power being disconnected, the Multiplus II / Quattro takes over the supply to the connected loads. This happens in less than 20 milliseconds such that computers and other electronic equipment will continue to operate without disruption. The second AC output is live only when AC power is available on the input side. Loads that should not discharge the battery, such as air-conditioning or a water heater can be connected to this output.  Up to 6 units can be connected in parallel in order to achieve higher power output. Three phase or split phase operation is also possible The Multiplus II / Quattro (via Color Control GX or Venus GX) can be monitored and controlled locally (via LAN) or remotely via the internet, using the VRM app and VRM portal website.
