Kehua at Clarvento

Kehua is a Chinese power electronics manufacturer founded in 1988. The brand develops PV inverters and energy storage systems for residential, commercial and utility applications. At Clarvento, the Kehua range mainly covers three-phase grid-tied inverters in several power classes and the iStoragE3 energy storage system, made up of a hybrid inverter and high-voltage battery modules.

This means you can source Kehua equipment for a home installation, a commercial project or a PV plant from one wholesale supplier.

Kehua grid-tied inverters

Kehua SPI on-grid inverters are three-phase units for systems that export surplus energy to the grid. The range includes models for homes and small businesses, inverters for commercial buildings and 1500 V units for utility PV plants.

SPI-B X2 series for homes and small businesses

The compact SPI-B X2 inverters cover the power range typical of detached houses, farms and small businesses. Two MPPTs let you connect strings with different orientations, such as two roof planes, and the IP66 enclosure makes outdoor installation straightforward. One example from this series is the Kehua SPI20K-B X2 20 kW grid-tied inverter. Check the product list for the power ratings currently available.

For the smallest three-phase systems, the range may also include SPI-B inverters rated at a few kilowatts.

Kehua inverters for commercial and industrial projects

For rooftops of warehouses and retail buildings, or ground-mounted systems next to production sites, Kehua offers SPI-B inverters from several dozen to over 100 kW. Selected models feature multiple MPPTs, support bifacial modules and include integrated DC and AC surge protection. For commercial projects we can quote the complete installation, not just a single inverter.

1500 V inverters for PV plants

For large solar plants, Kehua offers 1500 V string inverters with many MPPTs and enclosures built for harsh conditions. Selecting this type of inverter always requires a project review, so please send us your technical assumptions.

Kehua iStoragE3 energy storage

The iStoragE3 system combines a three-phase hybrid inverter with high-voltage LiFePO4 batteries. It is designed for homes and small businesses that want to increase self-consumption of solar energy and keep the power on during grid outages.

iStoragE3 hybrid inverters

iStoragE3 inverters feature a built-in energy management system (EMS) and backup power. The series comes in several power ratings, so you can match the unit to the grid connection and consumption profile. One example is the Kehua iStoragE3 10K hybrid inverter, which according to the manufacturer delivers up to 20 kW peak backup power with switchover below 10 ms. Check the other models' product pages for their parameters.

iStoragE B5-S2 battery modules

Kehua energy storage is built from iStoragE B5-S2 5 kWh battery modules. The modules use LiFePO4 cells with natural cooling, and the system can be expanded to 8 modules, or 40 kWh. It is worth planning the target capacity at the first selection, even if the customer starts with a smaller battery.

Which Kehua inverter or battery should I choose?

There is no single recommended Kehua model for every project. When you ask which Kehua inverter we recommend, we start with the system parameters:

• PV system size and planned DC/AC ratio,
• number and orientation of strings, plus module voltages and currents,
• a three-phase grid connection, as all Kehua inverters in our range are three-phase,
• storage now or later, which decides between a hybrid and a grid-tied inverter,
• backup requirements and the circuits that must stay powered during an outage,
• battery capacity matched to the consumption profile,
• installation location, ambient conditions, communication and monitoring,
• type of site: home, business, industrial facility or PV plant.

What do you need for a complete Kehua system?

A complete system is more than an inverter. A typical order includes:

• a grid-tied or hybrid inverter matched to the system size and string layout,
• for storage systems, the required number of iStoragE B5-S2 modules,
• an energy meter and communication accessories required by the manufacturer for the configuration (we confirm the compatible model during selection),
• DC and AC protection and cables and connectors,
• PV modules and mounting structures.

Where to buy Kehua

You can buy Kehua inverters and energy storage from Clarvento, a B2B photovoltaic wholesale supplier based in Wrocław, Poland, delivering components to installation companies in Poland and across Europe. We sell to installers, contractors and renewable energy partners. Once your business account is active, you can order online, and larger orders receive individual terms. Technical documentation is available on each product page.

Kehua - questions before you buy

Where can I buy Kehua inverters?

Kehua grid-tied and hybrid inverters and battery modules are available from Clarvento wholesale. The offer is aimed at businesses and a B2B account is required to place orders.

How much does a Kehua inverter or battery cost?

The price depends on the inverter power and battery capacity. The current net price is shown on each product page. An energy storage system costs the hybrid inverter plus the chosen number of battery modules, so for a complete system it is best to request a quote.

Which Kehua series should I choose?

SPI-B X2 grid-tied inverters suit homes and small businesses without storage. If the customer wants a battery now or later, an iStoragE3 hybrid inverter is the better choice. Commercial sites need higher-power SPI-B inverters, and PV plants 1500 V units.

Does Kehua offer single-phase inverters?

At present, all Kehua inverters in the Clarvento range are three-phase. If the site has a single-phase connection, ask us about an alternative.

Are iStoragE B5-S2 modules compatible with any inverter?

No. B5-S2 modules are part of the iStoragE3 system and are designed for the hybrid inverters in that series. Do not assume other combinations work without confirmation in the manufacturer's documentation.

Does Kehua energy storage provide backup power?

Yes, iStoragE3 hybrid inverters include a backup function. The power available during an outage depends on the model, battery capacity and switchboard configuration, so we define the backup scope during selection.

Can a Kehua battery be expanded?

Yes. The iStoragE3 system is expanded in 5 kWh modules, up to 8 modules. Please include the planned target capacity in your first enquiry.

Does Clarvento sell Kehua to installers?

Yes. We work with installers, contractors and renewable energy partners. After registering a B2B account you can order online or request a wholesale quote.

How can I check availability?

Availability is shown on each product page. Some units are supplied to order, and lead times for larger quantities are confirmed individually.
