What Off-Grid Solar Covers
PLB builds LiFePO₄ off-grid storage on self-developed cells — 5kWh to 500kWh systems at 90% depth of discharge, so a 5kWh pack delivers what 9kWh of lead-acid would; 4,000 to 6,000 cycles with a ten-year design life; MC4 connectors, reverse-polarity protection and automatic MPPT for one to two hour self-installation; 4G remote monitoring with 80% of faults fixed without a site visit; and operator-grade platforms that let one person manage 500 base stations. Ten-year TCO falls by up to 92% against diesel-backed lead-acid.
Seven Off-Grid Solar Sub-Scenarios
Each sub-scenario page covers the pain points that scenario faces, how PLB helps you solve them, a comparison table and the recommended models — so you can compare and choose faster.
Home Off-Grid Solar Storage
Five to ten kilowatt-hours a day for a whole home: 90% depth of discharge, ten-year design life and plug-and-play installation with no electrician required.
Community & Institutional Storage
Modular systems that expand from 10kWh to 100kWh without replacing existing units, with per-household prepaid metering and 80% of faults fixed remotely.
Telecom Base Station Storage
Diesel-replacement storage for remote base stations: 95% diesel displacement, −40 °C to 65 °C operation and an operator-grade platform where one person manages 500 sites.
Agriculture & Irrigation Storage
Irrigation costing a tenth of diesel with a 2–3 year payback: IP67 field protection against rodents and agrochemicals, and a water-plus-battery buffer that irrigates through cloudy days.
Island & Offshore Storage
3,000-hour salt-spray testing and 316L stainless construction for ten years of offshore service, IP68 immersion plus Category 12 typhoon fixing, saving ¥100,000+ a year in vessel costs.
Disaster Relief Storage
Suitcase-style systems deployed in 30 minutes by one person, solar self-sufficient so no fuel supply chain is needed, and certified for government reserve procurement.

Frequently Asked Questions
The questions EPC contractors and off-grid operators ask most about LiFePO₄ off-grid storage in the Off-Grid Solar scenario — 90% (depth of discharge) and 10-year (design life), and what it takes to qualify.
Will a PLB pack replace the lead-acid unit in the Off-Grid Solar scenario without rework?
The storage keeps the site DC bus voltage and stacks in modular units, and the inverter charge settings are documented for commissioning. Typical models for Off-Grid Solar builds are LL-OG-HOME5 and LL-OG-HOME10.
What runtime and output can we expect over a day in the Off-Grid Solar scenario?
Usable depth of discharge is about 90% against roughly 50% for lead-acid, so the same nameplate rating delivers close to twice the usable energy. Key figure: 90% (depth of discharge).
What temperature and ingress rating is specified for the Off-Grid Solar scenario?
The enclosure is rated for outdoor and remote-site duty, with BMS thermal protection and wide-temperature cells. Endurance: 10-year (design life).
Can the pack report SOC and alarms to monitoring already used in the Off-Grid Solar scenario?
The BMS and site controller report SOC, SOH and alarms remotely, so most faults are cleared without a site visit.
Which models cover the Off-Grid Solar scenario, and how is delivery handled?
Typical models are LL-OG-HOME5 and LL-OG-HOME10. Custom packs take 4–8 weeks including tooling, and lead time for standard models is confirmed on the quotation. Tell us the daily kilowatt-hour demand, peak load and site conditions — our engineers size the system and recommend the matching model within 24 hours.
