The SBC-7000 Series PV charge controller is designed for use with all types of photovoltaic panels and different types of batteries, such as wet or sealed lead acid, lead calcium, and lead antimony batteries.
The MCU (Microprocessor controller) is programmed with 3 stage charging algorithms and with 0~100% PWM (Pulse Width Modulation) duty cycles to provide the fastest, optimal charging current and voltages from PV panels according to the actual state of charge and type of battery.
The 3 stages (Bulk, Absorption, Float) and *Equalization* charging cycles ensure complete charging cycles and maintenance of lead acid battery automatically. Bulk and Float threshold charge voltage levels are user-adjustable to meet specific battery manufacturers' recommendations.*Equalization Charging is only for the wet type lead acid Battery, which automatically cycles once a month for 2 hours. Equalization Charging can be de-activated or re-activated manually.
Hence, maximum PV charging efficiency and longer service life span of the battery are ensured.Ampere Hour logging readouts in three sets, today and the last two days are shown on the LCD. This is useful to check the condition of PV data for efficiency and actual capacity of your system.
Electronic blocking of back current to PV and overcharging battery protection are standard.

RETURNS POLICY
To return goods we have delivered to you, please contact us within 30 days from the date you have received the item. A staff member will then assist you with any return or repair. This may include inspecting the goods, arranging for the goods to be sent for repair, or providing you with a replacement.
Incorrectly Ordered/Change Of Mind:
Refunds are not normally provided where you have simply changed your mind or found the goods cheaper elsewhere. However, if goods have been incorrectly ordered, at our discretion, customers may be credited less a restocking fee.
A change of mind return will only be accepted if:
Please note: For change of mind returns, the shipping cost and method is the customer's responsibility. We will not compensate any returns that are lost or damaged in transit to us. For some change of mind returns, a restocking fee may apply.
Faulty Items
We recommend you immediately inspect any goods that we deliver to you or that you collect from our store to ensure you are completely satisfied with the goods. If any goods arrive damaged, please contact us as soon as possible. We will arrange to have the damaged goods returned and either arrange for a replacement of the goods or refund. Replacements and refunds of new products that are damaged on delivery or faulty from new requires a proof of purchase of the product and be returned with all original packaging, accessories and/or manuals included. Refunds will be made via the method of payment you used to make your purchase. If we consider the goods to have breached a consumer guarantee, any shipping costs to return the goods to us will be at our cost and compensated.
Repairs
The product must be returned with proof of purchase, it must not be modified or mistreated in any way and it must not have been serviced elsewhere. Goods returned for repair will be assessed and/or repaired within a reasonable time. You may be required to pay labour, assessment and/or freight fees, such as where goods are assessed to have been damaged by misuse or accident. We may provide you with an approximate fee; this may vary due to reasons beyond our control. In some circumstances, goods presented for repair may be replaced by refurbished goods of the same type rather than being repaired. Refurbished parts may be used to repair the goods.
Estimated Delivery Time Frame: 4-8 business days
