The solution to be Presented is a Hybrid Solar Power solution.
Hybrid Solar solutions connect to the grid, and function like a normal electricity set up, powered by the Eswatini Electricity Company. However the power from EEC is only derived under the two conditions
There solar power generated by the panels is below the load
The batteries are depleted
Before these conditions are met your Home will take power 1st from the Sun and 2nd from the batteries. As the home primarily operating after sunlight the panels will be charging at least 70% from Sunlight. Meaning the batteries should be about 100% full by early morning and all security electronics and late night lighting will be kept ON during nighttime.
This will improve electricity efficiency toa value towards zero draw from the grid.
Fit to the solution, we combine the Solar Panel output to match the total load of the business, The panels will be mostly ground Mount Racked and we separating the project in to two (2) phases.
Features
Shading Mitigation: Up-down symmetrical module design Effectively reduce current mismatch due to shading
Lossless Cut: The cutting technology used was smooth and was without burrs. Low cell cracking risks, micro-cracking is reduced more than 50%.
Half Cut: Current density is reduced by ½, Internal power loss reduced to ¼ of conventional modules. Rated output power increased by 5-10W.
Galvanized Steel Frame: Rust-free frames with little to non-maintenance making the solution easy to live with long term.
Ultra High Voltage Panels
The hybrid inverter can control the charging and discharging process of batteries to transform AC and DC, and can directly supply power to AC loads to the DB with the grids.
The PCS controller communicates with the BMS through the CAN to obtain battery group status. Which you can view with you phone or computer via WiFi.
Features
Bi-directional Inverter: The inverter is meant to charge the batteries, pas though power from the Grid, switching taking a fast 10ms (tenth of a second)
EMS Function: Up-down symmetrical module design Effectively reduce current mismatch due to shading
RS485, CANBus Communication Interface: Good communication with the Battery management system to protect batteries from overcharge and minor surge.
Android, iOS Smartphone Ready: Watch your power generating system on your smarthphone to view behavior and trends.
Hybrid Inverter
Batteries store the energy you produce during the day, so you can draw power from the battery bank to run appliances when the sun isn’t shinning.
We only use Lithium Iron Phosphate Technology (LifeP04) batteries which are good for gradual discharge (last longer).
Features
Safe for the Environment: The Lithium Iron Phosphate battery is environmentally friendly and safe due to zero lead and no fumes when operational.
Service Life long: The product has a guarantee of 3,000 cycles (3,000 days or 8,2 years) wile performing at peak performance, later resulting at 80% efficiency till the lapse of 10-15 years.
Portable: A lithium iron phosphate battery is about 65% lighter than the normal Gel batteries and about half the volume while lasting longer.
Built-in-Safety: The Lithium Iron Phosphate Battery has a BMS with Breaker On/Off Switch for ultimate protection.
