2730W - 48V Off Grid Solar Kit - Power Inverter

The 2730W Off Grid Solar Kit comes complete with all the essential cables, switches and AGM batteries.

AGM Batteries are renowned for having a longer lifespan than traditional flooded lead acid batteries, with the added advantage of being spill proof and they also respond better to loading making them a good choice for running the kits power inverter.

The solar power is harnessed with high efficient, N-type TOPCon solar module with an impressive 30 year linear power warranty this is the range to fit and forget. Using the power of the sun and a state of art MPPT controller that intelligently regulates the working voltage of the solar panel this system can deliver approximately 228Ah on a 48V system per day during the summer months.

Monitoring of the system can be made easy with the optional remote meter or via Apple & Android smartphones, tablets, MacBook's and other devices, using the optional Bluetooth Adapter.

The TES series dual PV input controller is built for users who want more freedom in PV design without sacrificing charging performance. With two PV input channels on selected models, you can connect separate solar strings for better layout flexibility, or combine inputs to scale PV capacity within safe limits. This makes the controller a strong fit for RV systems, cabins, monitoring sites, and modular off grid power setups where roof space or panel orientation is not uniform. 

At the core, TES uses high efficiency MPPT tracking to maximize energy harvest across changing sunlight conditions. It automatically adapts to 12V 24V or 48V battery systems and provides multiple current options from 60A up to 100A, allowing you to match the controller to both compact and higher demand installations. High PV voltage input designs support longer strings, helping reduce wiring loss and simplify system layout. 

TES is also designed for modern battery choices. It works smoothly with lithium batteries and lead acid batteries, and supports BMS communication on compatible lithium packs for more accurate charging control. When batteries are unavailable or temporarily disconnected, the controller can operate in no battery mode, supplying power directly from PV when sunlight is sufficient. For growing systems, parallel connection of up to 6 controllers is supported, making future expansion straightforward. 

With isolated RS485 communication, optional Wi-Fi or 4G monitoring modules, and clear LCD local settings, TES helps users monitor system status, review energy records, and keep performance stable over time. The result is a dual PV input controller that supports flexible solar growth, dependable battery charging, and practical off grid operation.
