The SPF 3000TL LVM-ES module is Growatt’s cutting-edge, multi-functional off grid and solar inverter-charger, and serves as an essential component for any small to mid-sized power system. This model was designed specifically for residential systems, off-grid and solar systems, & self-consumption applications, and comes equipped with an MPPT solar charge controller, high-frequency pure sine inverter, a UPS function module, and more all in one compact unit.

The included WiFi module is a plug-and-play monitoring device able to be connected directly to your inverter, allowing you to monitor the status of your power system online or from your mobile phone anytime, anywhere. Plus, this inverter works with or without batteries, so you can create a power system tailored to your needs. Combine this 3kW inverter and charger with your PV array, stable grid connection, or favorite BigBattery battery to equip your home or camper van with a safe, reliable power system.

【Monitoring with Renogy ONE Core】 Add Renogy ONE Core to achieve smart energy monitoring with intuitive visuals and real-time data. It is an upgraded streamlined energy with our 3-in-1 smart panel.
【Self-Heating Function】 The intelligent self-heating function will start operating automatically once the battery’s core temperature drops below 41°F (5°C), effortlessly keeping your battery charged in cold environments. Plus, this function is powered by the Charger/Controller’s current instead of the battery itself.
【Premium BMS Circuit】 Incredibly advanced BMS provides over 20 protections designed to allow a peak current of 150A to pass through, deliver up to 1C charging and 1.3C discharging during an emergency. 50% more heat dissipation area will maximize the safety of your off-grid use. 
【The Ultimate Quality】 The next-level pouch cells surpass severe high temperature and puncture tests to avoid fire or explosion. The battery cell not only passes the UL1642 but also offers over ten years of lifespan with more than 4,000 cycles (80% DOD).
【Activation Switch】 With the activation switch cable, now for the first time, you can turn on or off multiple batteries in parallel to ensure the safety of installation and use.
【Auto-balancing Function】 Easily connect multiple batteries in parallel（up to 8）with the auto-balancing function, improving the average charging efficiency for your batteries in the long term.
【Enhanced Ways to Monitor】 You can connect the battery monitor directly via CAT cable without purchasing an additional coulometer. You can also use the BT-2 Bluetooth & DC HOME app to monitor multiple battery states in real-time.

The Dual Battery Sensing Isolator monitors both the starting battery and the auxiliary. If the unit detects that either battery has exceeded 13.2 volts, then the isolator will connect them. The benefit of the dual sensing feature allows user to charge the main battery from a solar panel or an external battery charger, on the auxiliary battery, once the auxiliary battery reaches 80% state of charge (13.2V). This ensures you never have a drained starter battery again. The isolator is also automatic and based on voltage, which saves installation time.   When the entire battery system drops below 12.7 volts the solenoid opens and isolates the starter battery from the auxiliary battery.

AIMS Power introduces its new battery product line of LiFePO4 batteries. The LiFePO4 batteries maintain constant output voltage, providing more efficient power. This allows the cell to deliver virtually full power until it is fully discharged without harming the battery, and it can greatly simplify or even eliminate the need for voltage regulation circuitry. The battery has a much longer cycle life capacity, and is easier to maintain compared to other battery technologies. The LiFePO4 technology has better thermal and chemical stability, which improves battery safety and packed with power in a small and lightweight footprint. Easily uses the same space as your existing 12V battery and replaces lead acid, AGM or Gel battery applications in RVs, boats, commercial vehicles, off grid back up power and much more. Not intended to replace starting batteries. Backed by an IEC rating that specifies requirements and tests for the safe operation of secondary lithium cells and batteries used in industrial applications including stationary applications.
