Please read this listing carefully and review the manual before purchase!

Highlights

• Designed to work with 48vDC battery banks
• Multifunction LCD display showing all AC & DC input/output parameters including LED indicators for operating status
• Can be programmed to work with lead acid, AGM, LiFePO4, or other common battery storage systems
• 120vAC output: 3500W pure sine inverter, 5000W surge rated
• 80A MPPT charge controller capable of handling up to 4400W of PV input @ 145VDC
• 2-wire autostart capable – will turn generators on/off automatically when programmed (compatible 2-wire autostart generator required)
• Integrated transfer switch with AC pass-through: powers your building while charging the battery bank with a generator or other AC power source
• Variable speed cooling fan
• On/Off rocker switch for AC output control
• RS485/CAN & USB connections with optional WiFi or Bluetooth data logger (sold separately unless otherwise stated)
• Protections: PV over current, PV reverse current, PV reverse polarity, AC input over voltage, AC input under voltage, short circuit, overload, and over temperature

Programmable Charging Modes

• Hybrid Charging (SNU – Default Setting): This mode is ideal for off-grid applications. The system will use solar PV to charge the battery bank when the sun is shining. If you start your generator, the generator will also charge the battery bank together with solar. At night or during periods of inclement weather, the generator can be started as needed & will charge the battery bank exclusively. 
• Solar Priority (CSO): This mode is used in a grid-tie application and uses solar PV during the day to charge the battery bank & power AC loads, and grid power at night to maintain the battery bank. 
• Grid Priority (CUB): This mode is used in a grid-tie application and uses grid power to keep the battery bank charged. If the grid power fails, the system reverts to solar PV battery charging. This would be similar to a UPS backup system. 
• Solar Only (OSO): This mode uses solar PV charging only. Charging with a generator or grid power is deactivated.

Output Modes

• Generator Priority (UTI – Default Setting): In an off-grid application, this mode will use the inverter power via the battery bank, and automatically switch to generator power to service AC loads when the generator is started. 
• Solar Priority (SOL): this mode will switch the output AC power to grid or generator if the solar PV isn’t sufficient. This mode is typically used in a grid-tied situation. 
• inverter Priority (SBU): this mode uses the inverter as priority AC output power, and will only switch to grid power if the battery bank voltage drops below the minimum preset level. 

Battery connection cable options:

#2 AWG Stranded copper cables – 5FT with #2 Copper Lugs.

Used for battery to inverter connections for the following systems:

The battery terminal connections and the inverter terminal connections require different sized #2 copper lug holes.  This cable pair is specifically designed and manufactured for these connections.

At this price point, the SRNE All-In-One units are popular. But they absolutely do not have the same features or functionality that a Magnum, Samlex, Schneider, Outback, or similarly well known and proven off-grid power system has. Read the manual included for download on this page, and compare it to other product features to ensure it will satisfy your needs. 

This unit will come preconfigured to use with off-grid power systems (solar + generator) by default. It will work “out of the box” when connected to your 24v battery bank and solar array, but customers will still need to program the unit to work with your specific battery bank (battery type, charge voltage, charge amperage, time setting, etc). 

Pure sine generators are recommended when used for battery charging. The use of open frame modified sine generators will still work provided the output is regulated @ 60hz. Also, the automatic battery charger default settings require connection to a 30A plug and wiring sized properly per the instruction manual. If you have a smaller generator that does not include a 30A plug, or you only have access to a standard 15A outlet, you will need to lower the maximum AC charge setting (parameter 28) in the system program menu. Failure to change this setting may trip the generator breaker as the current will exceed 15A when charging. 

The SRNE WIFI Adapter is included with this unit, but WE DO NOT PROVIDE ANY CONNECTION OR APP RELATED SUPPORT. If you plan to use the WIFI module, support is offered via SRNE exclusively. 

The Cabin Depot™ specializes in off-grid solutions only. Due to the variety of installation applications, we do not provide assistance with programming for connected equipment that is not provided by The Cabin Depot™. The installation manual is available for download and we encourage reading prior to purchase. If you plan to use this unit for any other application that is not specific to off-grid, customers need to seek proper approvals from your electric utility, local regulatory agency, and/or installer to ensure the use of this device is accepted for your specific application.
