The PV Generator is a hybrid power platform that brings together a three-phase PV inverter, an LFP battery storage interface and a true online UPS in a single cabinet, so operators can use solar energy, store it locally, and keep their AC loads running through grid outages, voltage fluctuation and frequency deviation.
The PV Generator is built for sites where the grid is unreliable, where diesel costs are climbing, or where carbon-compliance targets make renewable energy mandatory. It accepts a PV array on the DC side, an LFP battery bank for storage, and the utility mains or a backup diesel generator as the AC source, then delivers clean, stable three-phase AC power to the load.
Because the inverter, the storage interface and the UPS are integrated into one cabinet, the system replaces a small equipment room full of separate boxes. Cabling is simpler, the footprint is smaller, and the engineering risk of mismatched components is removed at the source.
Operators typically deploy the PV Generator in livestock farms, poultry houses and crop-irrigation sites, in telecom base stations and microwave relay sites, in small factory production lines, in rural clinics and schools, and in off-grid residential estates where the grid is either absent or unreliable.

The PV Generator sits between four energy sources and the load. Solar PV feeds DC power directly into the inverter, charging the battery bank whenever the sun is producing more than the load is consuming. The battery bank then discharges when PV is unavailable, when the grid drops out, or when tariffs are at their peak. The mains acts as a slow charger and a backup, while an optional diesel or gas generator can be wired in as the last-resort backup for extended outages.
An output isolation transformer is built into the cabinet, providing galvanic isolation between the DC bus and the AC load. This delivers clean sine-wave output with strong immunity to load-side noise, surge events and lightning transients, which is particularly important for livestock buildings, irrigation controllers and remote telecom shelters where poor power quality is the rule rather than the exception.
A static switch at the output performs the seamless transition between the inverter and the bypass mains. When the grid goes out, the load never sees the change. When the sun comes back, the system reverts to PV priority automatically. The result is power that behaves like a true online UPS but is fuelled by the sun.

The PV Generator is engineered around high-voltage LFP battery chemistry. LFP cells offer long cycle life, inherent thermal stability and predictable performance in hot or cold outdoor enclosures, which makes them the right choice for farms, telecom towers and remote industrial sites where the cabinet may sit in an unconditioned equipment room.
An intelligent battery management system supervises every cell. Charge and discharge windows can be customised by the operator, so the system charges when solar is plentiful or when tariffs are low, and discharges when tariffs peak. This converts the battery from a passive backup device into an active energy-trading asset.
Because the same battery bank powers both the green-energy cycle and the UPS function, you pay for storage once and gets two services from it. The system also accepts an oversized PV array on the DC side, which lets the customer oversize solar and clip the surplus into the battery, a common configuration in high-irradiance regions where the site can absorb far more solar than the inverter can process at any one moment.

The PV Generator delivers a true sine-wave AC output. Harmonic distortion is held to a low level on linear loads, which protects sensitive equipment such as variable-frequency drives, refrigeration compressors, milking robots, laboratory instruments and telecommunications gear from the degradation and overheating that cheaper modified-sine inverters cause.
Transfer time between sources is essentially instantaneous, so computers, point-of-sale terminals and process controllers see no interrupt at all. This is the same behaviour you expect from a true online double-conversion UPS, and it removes one of the historical objections to using a renewable-energy inverter for mission-critical loads.
Dual-DSP digital control keeps the inverter and the static switch tightly coordinated. The control loop is fast enough to react to load steps, motor starts and lightning-induced transients, and it logs each event with a precise time stamp so operators can review what happened and when.

Where the grid is present but tariffs vary sharply across the day, the PV Generator can be programmed to charge the battery when tariffs are low and discharge when tariffs are high. The result is a daily peak-shaving cycle that reduces the imported energy during the most expensive hours and lowers the monthly utility bill without any change to the load.
Self-use mode maximises the fraction of the load that is supplied directly by PV or by stored solar energy, rather than by the grid. This is the configuration of choice for farms, factories and commercial buildings with sustainability goals, because it both cuts the electricity bill and reduces the site carbon footprint at the same time.
For sites that already operate under a corporate ESG framework, the monitoring platform exports per-day and per-month energy mix data in a format that drops straight into sustainability dashboards. Compliance teams get an evidence trail for green energy claims without having to maintain a separate metering system on site.

Weak-grid regions present two challenges for renewable-energy systems: voltage can sag or surge at the point of common coupling, and frequency can drift when small local generators are loaded and unloaded. The PV Generator is engineered to operate through both conditions without disconnecting, which is the single biggest reason that cheaper inverters trip offline during the very conditions where backup power is most needed.
In off-grid applications the system runs purely on PV and battery, with the optional backup generator wired in only for extended cloud cover or seasonal low-irradiance periods. The PV Generator is widely used in African livestock farms, in European remote dairy operations, in island microgrids and in telecom shelters at the edge of the grid where extending the utility network is uneconomic.
Safe isolation protection is built into the cabinet. Lightning protection, surge protection and electric-shock protection are all provided through the output isolation transformer and the integrated protection devices, which makes the system safe for operator use even in buildings where the existing wiring is old or non-standard.

A single PV Generator unit covers the small to mid power range common in farms, telecom sites and small factories. When the load grows, up to six units can be connected in parallel to deliver a proportionally larger output, without having to replace the original installation or retrain the operating team.
The parallel architecture also provides redundancy. In critical applications such as poultry incubators, dairy milking parlours, irrigation pumping stations and cellular base stations, the failure of a single module does not interrupt the load because the remaining units share the work. Service work can be performed on one module while the others continue to run.
Cabinet footprint and cable entries are designed for outdoor and semi-outdoor installation. Castors at the base allow the unit to be rolled into position on site, and the integrated cable landing points accept the standard gland sizes used in agricultural, telecom and light-industrial wiring.

The PV Generator carries an LCD touchscreen on the front panel that gives operators a real-time view of PV input power, battery state of charge, mains status, generator status, load power and any active alarm. One-touch setup walks the operator through commissioning in minutes, and the same panel is used for daily checks, alarm acknowledgement and parameter review.
Optional remote monitoring cards allow the system to be supervised from a control centre, an agricultural co-op office or a telecom network operations centre. Status, alarms and energy-mix data are exposed through standard industrial protocols so the system drops into existing SCADA or building management platforms with minimal integration effort.
Maintenance is designed to be straightforward. The internal layout places fuses, contactors, fans and the BMS service port within easy reach of a technician with a standard tool kit. The long-cycle-life LFP battery, the air-cooling design and the low-noise operation all reduce the lifetime cost of ownership for you.

The following answers explain how the PV Generator is positioned for operators evaluating a hybrid PV inverter for off-grid, weak-grid, peak-shaving and farm-power applications.
Q: What does the PV Generator actually do?
It combines a three-phase PV inverter, an LFP battery storage interface and an online UPS in a single cabinet. Solar energy is converted to AC for the load, surplus is stored in the battery, and the load is kept running through grid outages and voltage fluctuations without any interruption that the connected equipment can see.
Q: How does the system switch between PV, battery, grid and generator?
An internal static switch moves the load between the inverter and the bypass mains in essentially zero seconds. PV is prioritised automatically when solar energy is available, the battery takes over when PV is insufficient or tariffs are high, the grid is used as a slow charger and backup, and an optional diesel or gas generator can be wired in for extended low-irradiance periods.
Q: Where is the PV Generator typically deployed?
The most common deployments are livestock and dairy farms, poultry houses, crop irrigation pumping stations, telecom base stations and microwave relay shelters, small factory production lines, rural clinics and schools, off-grid residential estates and remote control rooms where the grid is absent or unreliable.
Q: Is the PV Generator suitable for weak-grid and off-grid sites?
Yes. The system is engineered to tolerate wide voltage sag and surge, frequency drift and extended outage events. It is widely used in weak-grid regions across Southern Africa, Eastern Europe and Southeast Asia, and in off-grid microgrids where extending the utility network is uneconomic.
Q: Can multiple units run in parallel for higher power?
Yes. Up to six PV Generator units can be connected in parallel to deliver a proportionally larger output. Parallel operation also adds redundancy for critical-load applications, because the remaining units share the work if one module is taken offline for service.
Q: How is the battery charged and managed?
An intelligent battery management system supervises every cell of the high-voltage LFP battery bank. Charge and discharge windows are customisable, so the system charges when solar is plentiful or when tariffs are low and discharges when tariffs peak. The BMS also balances cells, protects against over-charge and over-discharge, and logs events for service review.
Q: How is the system monitored and controlled?
Locally, an LCD touchscreen on the front panel shows live PV, battery, mains, generator and load status and accepts operator commands. Remotely, optional communication cards expose the same data through standard industrial protocols to a control centre, an agricultural co-op office or a telecom network operations centre.
Q: What is the expected service life of the system?
The high-voltage LFP battery is specified for very long cycle life and is supervised by an intelligent BMS, which together minimise the lifetime replacement cost. Air cooling, low-noise operation and a service-friendly internal layout further reduce the total cost of ownership for you.
This PV Generator is engineered to support operators operating under GDPR, ISO/IEC 27001, NIST SP 800-53, SOC 2 and similar privacy and security regimes. The local LCD control panel keeps sensitive power and battery telemetry on premises; only aggregated, non-personal operational metrics are forwarded to optional remote monitoring under your data retention policy. Optional TLS-encrypted uplinks, role-based operator accounts with audit trails, and tamper-evident cabinet hardware help you evidence physical and logical controls during your team or a regulator.
