Site survey
We record roof or ground space, daily load, backup hours, and whether the site is on-grid, hybrid, or fully off-grid.
Solar Energy
Lease solar power, store it on site, and cut diesel costs — without a large capital outlay.

Clean Power That Stays On
Grid instability and diesel generation remain everyday costs for homes, offices, factories, and telecom sites across Afghanistan. RNK’s solar programme combines photovoltaic supply, lithium storage, and a lease model so clients can move to clean power without buying the whole system on day one.
We survey the site, size the array and battery, install the equipment, and stay responsible for commissioning and after-sales support. You pay for the energy saved — not for a warehouse of unused hardware.
- Zero-upfront solar energy saving lease for qualified sites
- LiFePO4 home and commercial storage with a 10-year warranty
- Survey, installation, commissioning, and local technical support
- Hybrid and off-grid modes for homes, offices, and telecom loads
How the Solar Lease Works
The lease is built for operators who need reliable power now, but do not want to lock capital in a one-off equipment purchase.
System design
RNK sizes PV modules, inverters, and a matching lithium battery so daytime generation and night-time backup stay in balance.
Install & commission
Certified technicians mount the array, wire the storage cabinet, test protection settings, and hand over the monitoring app.
Pay for savings
You adopt green power with no large capital outlay and pay against the diesel and grid cost the system actually displaces.
Built-In Features
Every RNK solar system is commissioned with the same control, communication, and protection stack so operators learn one interface.
2A active balancing
Keeps every cell in the string at the same voltage during daily cycling, which protects capacity and extends calendar life.
Bluetooth and app
Staff can read state of charge, alarms, and charge mode from a phone without opening the cabinet.
Touchscreen control
A CTP display on the unit sets off-grid or hybrid behaviour and multiple charge and discharge profiles.
Layered protection
Over-charge, over-discharge, over-current, over-voltage, and temperature cut-outs are built into the BMS.
Where We Install
The same storage platform covers quiet residential loads and harsher commercial duty. RNK matches panel count, inverter type, and battery size to the circuit you actually need to keep alive.
Homes — lighting, refrigeration, pumps, and evening backup when the grid drops.
Offices and shops — keep POS, IT, and climate systems running through outages.
Telecom — cut diesel hours on BTS sites, microwave hubs, and network rooms.
Industry — support selected production lines and cold rooms without oversizing a generator.
Remote sites — off-grid camps, field offices, and grassland or border locations.
Operating Envelope
Shared technical limits for the storage systems we install. Voltage and power can be tailored to the inverter and load on each site.
Temperature
Charge between 0°C and 50°C. Discharge between −20°C and 60°C. Natural air cooling, IP20 indoor installation, floor-standing.
Communication
RS485, RS232, CAN, and Bluetooth for inverter pairing, remote alarms, and mobile commissioning.
Compliance
MSDS, UN38.3, and IEC documentation. Ten-year product warranty with RNK installation and service cover in Kabul and the regions we operate.
Tell us the load. We will size the system.
Share your site type, daily kWh, and how many hours of backup you need. RNK will size the storage, a matching solar array, and either a lease or an outright supply.
