ABB inverters offer wide voltage ranges, and two MPPT circuit inputs, increasing flexibility in module installation and string sizing. Most inverters are configurable for 240 VAC single-phase, 208 VAC three-phase, or 277 VAC single-phase output.

ABB PVI Series grid-tie inverters feature high energy yield and performance efficiencies of up to 97%. These inverters have a field-adjustable “start-up voltage” point that allows low-end PV operating voltage down to 90 VDC. While there is some loss of efficiency at lower voltage settings, inverters can operate with as few as five standard 60-cell modules in series. Please see the inverter sizing chart in the System Design section for configurations that work in most areas. All ABB inverters come with a 10-year warranty.

ABB PVI and UNO Transformerless Inverters

The ABB PVI and UNO series of inverters are some of the most flexible string inverters available. These ABB inverters have two separate MPPT inputs, allowing for two sub-arrays to be configured with differing string lengths, orientations, or even different PV modules. Conditions on one MPPT will not affect the other. Additionally, the 5 kW and larger inverters have two input terminals for each separate MPPT section allowing as many as four strings of modules (two on each MPPT) to be connected without separate string fusing. Both MPPT inputs can also be paralleled for use with a single array. A wide input voltage range allows for smaller installations with reduced string sizes where needed.

An integrated LCD displays real-time operating parameters, and RS-485 and USB interfaces can connect remote monitoring systems. An integrated DC disconnect is standard on all models shown here. ABB inverters can produce full-rated power at ambient temperatures up to 122 °F (50 °C). The fan-less design and NEMA 4X enclosure enable deployment in extreme environments. Output voltage can be set for 240 VAC split-phase, or 208 VAC or 277 VAC (480 VAC WYE) for three-phase systems (three inverters required for phase balancing).

Where NEC 2014 690.12 rapid shutdown code requirements have been adopted, ABB has introduced two new versions of the ABB Rapid Shutdown Box which cuts off DC voltage and current between the array and the inverter when activated. ABB transformerless single-phase inverters are available in sizes covering most common residential requirements, and can be used in groups of three for commercial three-phase applications. The transformerless design reduces internal power losses for high efficiencies. Output voltage can be set to 240 VAC split-phase, or 208 VAC or 277 VAC (480 VAC WYE) for three-phase systems.

Features:
  • Available in sizes from 3 kW to 8.6 kW with dual-MPPT DC intputs
  • Internal Arc Fault Circuit Interrupter (AFCI) for added safety per NEC 2011
  • Field selectable 208, 240 or 277 VAC output
  • RS485 Communications interface included
  • Operating temperatures of -13 °F to +131 °F (-25 °C to +55 °C)
  • Active and reactive power control, low voltage ride-through
  • 10-year warranty
  • Listed to UL 1741-2010 for U.S.A. and Canada
  • Compliant with: IEEE 1547-2003, IEEE 1547.1, UL1699B-2013, ANSI/IEEE C62.41, FCC Part 15 A & B, C22. 2 No. 107.1-01 (Sept. 2011)

Shipping Policy:

When you place an order, you will receive a confirmation email of that order. This indicates that we have received your order in our system. Once your order has been received, we will contact our suppliers to determine whether that item is in stock and available to ship.

If your purchased item(s) are unavailable, we will notify you of other options that are available. If the item(s) are available for shipment (usually in 5 business days or less), we will inform our suppliers to ship the order directly to you.

Once we have confirmed that the order is in stock, we will email you the tracking number within one business day of your order leaving the warehouse. If you do not receive an email with the tracking information from us within 7 business days from when you placed the order, please follow up with us at orders@SolarTechDirect.com.

Most orders are shipped via UPS or FedEx ground shipping to your designated shipping address. Larger items, such as solar panels (150W and above) and water heating tanks, must ship by freight, which is very costly. These items are not eligible for free shipping.

When the shipment arrives, the driver will ask you to sign for the delivery. This is a legal document stating that the package is being delivered in good condition without damage and that you are waiving any additional claim from the shipper. Before signing, inspect the package(s) closely on all sides. Note any damage, including scuffs, dents, tears, punctures or creases on the delivery receipt. If you sign for damaged goods without making a damage notation, we may not be able to help you persue a damage claim. Your signature on a shipping receipt is a legal release of claim for damage unless noted at the time of receipt. So check your delivery carefully.

If there is anything unusual with the package, you have the right to open it to inspect the contents. If the driver is unwilling to wait while you inspect all of the items, you may mark on the delivery receipt “Concealed Damage Possible”. If there is damage to the shipment, then you must contact SolarTech Direct immediately.

YOU MUST NOTIFY US WITHIN 48 HOURS OF THE DELIVERY DATE & TIME FOR ANY DAMAGE CLAIMS. OTHERWISE WE WILL NOT BE ABLE TO FILE A CLAIM WITH THE CARRIER AND ISSUE A REPLACEMENT.

Order Cancellation Policy:

A $50 administration fee will be applied if you cancel your order after 48 hours regardless if your order has been shipped or not. If the supplier has shipped your order, you (the purchaser) will have to pay the shipping charges for returning the product plus a 15% restocking fee. We will only issue refunds to the credit card you used to place the order.

Return Policy:

We hope you are satisfied with your purchase from SolarTech Direct. You may return most items for a full refund, minus shipping and handling charges and a 15% restocking fee, within 30 days from date of purchase. All items must be unused and in original condition in the original packaging. Special orders and custom built orders are not returnable. If shipping charges were part of your order, they are not refundable. Some manufacturers are excluded from the 30-day return policy. The product description will note if there is an exclusion and their specific return policy. Please see section below for items that are not eligible for returns.

Customer returns for items received as part of a "free shipping" offer will be credited for the amount of the returned items less actual outbound shipping charges paid by us and any restocking fee and other costs as mentioned above that may apply.

Please email us at returns@solartechdirect.com to receive a Return Merchant Authorization (RMA) number. Returns will not be processed without an RMA. We will also provide you with the address to return the item. Please note, you will be responsible for the return shipping and handling costs.
