AL12+ Series Offgrid Solar Cabinet (10kVa / 400A)

Heavy Duty Cabinet - Indoor or outdoor installation thanks to IP protection rating and additional rain hood - Fully welded construction, 3mm aluminium - Stainless steel bolts and fittings installed throughout - Powder coated light grey finish (RAL7035) - Double front doors with segregation between battery section and equipment section - Robust 3-point locking system - Rain protected vents on either side and on top to facilitate passive and forced ventilation, with removable covers - Stainless steel lifting eyes on all four corners on top - Document pocket on inside of door - Dust filters installed on inlet and outlet vents - Ventilation fans installed as standard, with easily programmable temperature on/off settings - Punched aluminium screens over all openings to prevent unwanted entry by insects High Powered Victron Inverter / Charger At the heart of the system lies a Victron MultiPlus-II 48V inverter/charger (10kVa). These inverters feature a low frequency, super robust toroid transformer that has been proven to handle heavy loads and high surge/startup currents. The inverter is ultra efficient (95%) and has a small zero load power consumption, ensuring very little power is wasted when converting 48V DC battery power to 230V AC mains power. All Victron MultiPlus-II units also feature a 230V AC input connection and integrated high power battery charger plus transfer switch. This allows you to connect a generator to charge the batteries when they get low during times of reduced sunlight. The inverters also have a unique feature called Power Assist, which lets you blend inverter power and generator power together for a very high power demand. For example, an 8kVa inverter plus a 10kVa generator can run a load of up to approximately 18kVa, where neither the inverter or generator could do so on their own. Ultra Efficient Victron MPPT Solar Charger Especially in the case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30% compared to PWM controllers and by up to 10% compared to slower MPPT controllers. The Victron MPPT solar controllers also feature a wide PV operating voltage (120VDC - 450VDC) to accommodate a wide range of panel combinations and configurations. Advanced Monitoring System Instantly and easily monitor battery state of charge, AC power consumption, DC power consumption, solar power generation, AC input (generator) power and temperature. All this data is displayed on the easy to read 5" touch screen. If your system is connected to the internet via wifi or ethernet cable, you can also view all live and historic data on Victron's web portal (VRM Online): ensure your system is working correctly, monitor faults and alarms in realtime and in the past, analyse how much power you are using and generating, help decide if you need additional battery or solar during different times of the year, and receive email alerts on a wide range of parameters and alarms. An online system also allows us to assist and offer quick and effective support from our office: we can log in remotely to diagnose problems, troubleshoot, offer assistance and even change settings to minimise problems and downtime. Auto Generator Start The system also features a powerful generator autostart interface (please note: you must have a compatible generator with a 2-wire autostart interface built in). This allows you to stop and start the generator on a wide range of parameters such as low battery or high power being drawn. These settings can easily be accessed by the user via the 5" touch screen. CANBUS Operation for Safety and Reliability When using our cabinet offgrid systems with managed batteries such as Pylontech US5000, the batteries, inverter/charger, MPPT and monitoring system all link together via a CANBUS communication interface. This allows the batteries to take control of all the Victron charging and inverting equipment: the batteries tell the solar charger what voltage to charge at and can increase, reduce or stop the charging current as required, which results in an ultra safe and reliable system. For example, if it is very cold, lithium batteries like to be charged at a lower charge rate until they warm up, so in the middle of winter the batteries will tell the MPPT charger via the CANBUS communication to reduce the charge rate until it is suitable to ramp up. From our experience with offgrid systems for over 10 years, fully managed battery systems using CANBUS communications are the most reliable and effective type of offgrid setup, with problems and issues greatly reduced. Pylontech Lithium Batteries We highly recommend Pylontech US5000B lithium batteries. After many years in the field we have found them to be extremely reliable with very few problems and failures. Each battery is 48V 5kWh (4.8kWh usable) and designed to be modular: simply link as many as you want together to make whatever size battery bank you like, and unlike lead acid batteries you can easily add additional batteries later to increase your overall storage capacity without affecting the existing batteries. With 6000+ cycle life, high continuous discharge ratings, large surge capabilities, high charge rate, wide operating temperature range, ultra efficiency and a reliable BMS, these are one of the best and safest choices when it comes to lithium batteries for offgrid solar. If one Pylontech module fails, that module alone shuts down, allowing you to continue to run off the remaining batteries, and you will receive an alarm on your monitoring system indicating which battery has failed.
