Conclusions This paper presents an energy management strategy for an off-grid (PV battery) energy system. Its main objective was to control the different loads according to the forecasting of the energy availability of the system and the prediction of the battery SOC at peak hour and the total power to be delivered the next day by the PV panels.
This paper concludes that the choice of charging strategy depends on the specific requirements and limitations of the off-grid solar PV system and that a careful analysis of the factors that affect performance is necessary to identify the most appropriate approach.
Here are some steps to follow when designing batteries in off-grid solar PV systems: Determine the energy needs: Calculate the amount of energy needed to power the load (s) in the system, considering factors such as the time of day, weather conditions, and seasonal variations .
The battery storage system plays a critical role in the performance and reliability of off-grid solar PV systems, ensuring a consistent and reliable supply of electricity . Effective battery charging strategies are essential to ensure optimal battery performance and longevity in off-grid solar PV systems.
Off-grid solar PV systems are increasingly popular in remote areas where grid connectivity is unreliable or nonexistent . These systems use batteries to store excess solar energy generated during the day, which is used to power devices and appliances at night or during overcast weather conditions.
The hybrid system consists of a photovoltaic (PV) module, a LiFePO4 battery pack coupled with a Battery Management System (BMS), a hybrid solar inverter, and a load management control unit. A Long Short-Term Memory network (LSTM)-based forecasting strategy is implemented to predict the available PV and battery power.

Solar systems explained
The main components of a solar system. All solar power systems work on the same basic principles. Solar panels first convert solar energy or sunlight into DC power using what is known as the photovoltaic (PV) effect. The DC power can then be stored in a battery or converted into AC power by a solar inverter, which can be used to run home appliances.
