Company & Service Facts
Yangzhou Weikechuang Photovoltaic New Energy Co., Ltd. publishes product and system-selection information for residential backup, commercial storage, telecom and monitoring sites, and remote off-grid power. A project should confirm load, daily energy use, backup time, local solar conditions and installation environment before model selection and quotation.
Solar Solution Scenario Simulation
Explore practical solar storage scenarios for residential backup, commercial energy storage, telecom backup power and remote off-grid power supply.
PV → Controller → Battery → Inverter → Load
Residential Solar Storage
Suitable for home outage backup, rural rooftop PV and small off-grid loads. System matching can be based on daily energy use, backup time and installation conditions.
Home backup and daily solar self-use, with priority on safety, quiet operation and stable power.
Solar System Design Library
Practical system configuration, wiring logic and selection references for project developers, installers and B2B solar storage buyers.
Shows the basic connection relationship between PV modules, controller, inverter, battery bank and AC loads.
Request Design ReferenceHelps evaluate backup time, depth of discharge, system voltage and battery bank capacity.
Request Design ReferenceSupports preliminary review of module voltage, current, controller input range and cable direction.
Request Design ReferenceIncludes common 5KW / 10KW / 20KW off-grid system configuration templates.
Request Design ReferenceOff-grid Solar System Calculator
Estimate the first configuration from daily energy use, maximum load power, backup days, sunlight condition and battery type.
Move the sliders and the estimate updates instantly for PV power, battery capacity, inverter size and system voltage.
Daily Energy Consumption
5 kWh
Maximum Load Power
3000 W
Backup Days
2 Days
Sunlight Condition / Region
Formula note: PV power = daily kWh x 1000 / 4 peak sun hours x sunlight factor. Battery capacity = daily kWh x backup days / usable DOD. Inverter size = peak load x 1.25, rounded up to a common specification.
Ready for quotation review: 1630Wp PV / 20.0kWh battery / 5000W inverter.
Solar Panel Power
1630Wp
Battery Capacity
20.0kWh
Inverter Power
5000W
System Voltage
48V
Approx. 420Ah @ 48V
These results are preliminary estimates. Final design should review load type, surge current, installation environment, sunlight conditions and budget.

FAQ
Sizing starts with daily energy consumption, maximum load power, required backup days and local sunlight conditions. Load surge current, installation environment, battery type and budget should also be reviewed.
Gel or lead-acid batteries are common for stable and cost-sensitive backup systems. Lithium batteries are better when higher cycle life, lighter weight and higher usable depth of discharge are required.
Yes. The page is designed for B2B inquiries covering solar panels, storage batteries, inverters, MPPT controllers and off-grid system matching.
Send load power, daily energy use, backup time, country or region and installation scene so we can prepare the first configuration direction.
